Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580134, here are decompositions:
- 23 + 31580111 = 31580134
- 41 + 31580093 = 31580134
- 71 + 31580063 = 31580134
- 83 + 31580051 = 31580134
- 167 + 31579967 = 31580134
- 281 + 31579853 = 31580134
- 431 + 31579703 = 31580134
- 491 + 31579643 = 31580134
Showing the first eight; more decompositions exist.
