Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540320, here are decompositions:
- 11 + 31540309 = 31540320
- 23 + 31540297 = 31540320
- 59 + 31540261 = 31540320
- 79 + 31540241 = 31540320
- 103 + 31540217 = 31540320
- 107 + 31540213 = 31540320
- 109 + 31540211 = 31540320
- 113 + 31540207 = 31540320
Showing the first eight; more decompositions exist.
