Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588424, here are decompositions:
- 67 + 31588357 = 31588424
- 73 + 31588351 = 31588424
- 103 + 31588321 = 31588424
- 157 + 31588267 = 31588424
- 223 + 31588201 = 31588424
- 337 + 31588087 = 31588424
- 421 + 31588003 = 31588424
- 463 + 31587961 = 31588424
Showing the first eight; more decompositions exist.
