Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605032, here are decompositions:
- 3 + 31605029 = 31605032
- 13 + 31605019 = 31605032
- 31 + 31605001 = 31605032
- 73 + 31604959 = 31605032
- 229 + 31604803 = 31605032
- 313 + 31604719 = 31605032
- 421 + 31604611 = 31605032
- 499 + 31604533 = 31605032
Showing the first eight; more decompositions exist.
