Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574692, here are decompositions:
- 3 + 31574689 = 31574692
- 5 + 31574687 = 31574692
- 11 + 31574681 = 31574692
- 53 + 31574639 = 31574692
- 239 + 31574453 = 31574692
- 263 + 31574429 = 31574692
- 389 + 31574303 = 31574692
- 431 + 31574261 = 31574692
Showing the first eight; more decompositions exist.
