Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492408, here are decompositions:

  • 37 + 2147492371 = 2147492408
  • 79 + 2147492329 = 2147492408
  • 109 + 2147492299 = 2147492408
  • 379 + 2147492029 = 2147492408
  • 571 + 2147491837 = 2147492408
  • 577 + 2147491831 = 2147492408
  • 709 + 2147491699 = 2147492408
  • 811 + 2147491597 = 2147492408

Showing the first eight; more decompositions exist.
