Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497650, here are decompositions:
- 13 + 31497637 = 31497650
- 73 + 31497577 = 31497650
- 103 + 31497547 = 31497650
- 109 + 31497541 = 31497650
- 127 + 31497523 = 31497650
- 181 + 31497469 = 31497650
- 241 + 31497409 = 31497650
- 313 + 31497337 = 31497650
Showing the first eight; more decompositions exist.
