Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604858, here are decompositions:
- 127 + 31604731 = 31604858
- 139 + 31604719 = 31604858
- 211 + 31604647 = 31604858
- 349 + 31604509 = 31604858
- 487 + 31604371 = 31604858
- 499 + 31604359 = 31604858
- 547 + 31604311 = 31604858
- 577 + 31604281 = 31604858
Showing the first eight; more decompositions exist.
