Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539124, here are decompositions:
- 41 + 31539083 = 31539124
- 137 + 31538987 = 31539124
- 173 + 31538951 = 31539124
- 317 + 31538807 = 31539124
- 431 + 31538693 = 31539124
- 563 + 31538561 = 31539124
- 647 + 31538477 = 31539124
- 797 + 31538327 = 31539124
Showing the first eight; more decompositions exist.
