Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604430, here are decompositions:
- 43 + 31604387 = 31604430
- 47 + 31604383 = 31604430
- 59 + 31604371 = 31604430
- 71 + 31604359 = 31604430
- 73 + 31604357 = 31604430
- 83 + 31604347 = 31604430
- 89 + 31604341 = 31604430
- 127 + 31604303 = 31604430
Showing the first eight; more decompositions exist.
