Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567802, here are decompositions:
- 61 + 31567741 = 31567802
- 73 + 31567729 = 31567802
- 103 + 31567699 = 31567802
- 109 + 31567693 = 31567802
- 181 + 31567621 = 31567802
- 199 + 31567603 = 31567802
- 373 + 31567429 = 31567802
- 433 + 31567369 = 31567802
Showing the first eight; more decompositions exist.
