Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474568, here are decompositions:
- 19 + 31474549 = 31474568
- 67 + 31474501 = 31474568
- 79 + 31474489 = 31474568
- 211 + 31474357 = 31474568
- 277 + 31474291 = 31474568
- 397 + 31474171 = 31474568
- 439 + 31474129 = 31474568
- 457 + 31474111 = 31474568
Showing the first eight; more decompositions exist.
