Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586162, here are decompositions:
- 31 + 31586131 = 31586162
- 61 + 31586101 = 31586162
- 103 + 31586059 = 31586162
- 109 + 31586053 = 31586162
- 199 + 31585963 = 31586162
- 313 + 31585849 = 31586162
- 379 + 31585783 = 31586162
- 499 + 31585663 = 31586162
Showing the first eight; more decompositions exist.
