Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576750, here are decompositions:
- 11 + 31576739 = 31576750
- 41 + 31576709 = 31576750
- 47 + 31576703 = 31576750
- 131 + 31576619 = 31576750
- 167 + 31576583 = 31576750
- 239 + 31576511 = 31576750
- 311 + 31576439 = 31576750
- 347 + 31576403 = 31576750
Showing the first eight; more decompositions exist.
