Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497782, here are decompositions:
- 31 + 31497751 = 31497782
- 61 + 31497721 = 31497782
- 103 + 31497679 = 31497782
- 109 + 31497673 = 31497782
- 181 + 31497601 = 31497782
- 223 + 31497559 = 31497782
- 241 + 31497541 = 31497782
- 313 + 31497469 = 31497782
Showing the first eight; more decompositions exist.
