Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576774, here are decompositions:
- 23 + 31576751 = 31576774
- 71 + 31576703 = 31576774
- 101 + 31576673 = 31576774
- 191 + 31576583 = 31576774
- 233 + 31576541 = 31576774
- 263 + 31576511 = 31576774
- 347 + 31576427 = 31576774
- 401 + 31576373 = 31576774
Showing the first eight; more decompositions exist.
