Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423804, here are decompositions:
- 61 + 2147423743 = 2147423804
- 103 + 2147423701 = 2147423804
- 157 + 2147423647 = 2147423804
- 241 + 2147423563 = 2147423804
- 271 + 2147423533 = 2147423804
- 373 + 2147423431 = 2147423804
- 457 + 2147423347 = 2147423804
- 523 + 2147423281 = 2147423804
Showing the first eight; more decompositions exist.
