Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577266, here are decompositions:
- 3 + 31577263 = 31577266
- 5 + 31577261 = 31577266
- 107 + 31577159 = 31577266
- 137 + 31577129 = 31577266
- 257 + 31577009 = 31577266
- 317 + 31576949 = 31577266
- 557 + 31576709 = 31577266
- 563 + 31576703 = 31577266
Showing the first eight; more decompositions exist.
