Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540524, here are decompositions:
- 23 + 31540501 = 31540524
- 31 + 31540493 = 31540524
- 53 + 31540471 = 31540524
- 83 + 31540441 = 31540524
- 107 + 31540417 = 31540524
- 181 + 31540343 = 31540524
- 227 + 31540297 = 31540524
- 263 + 31540261 = 31540524
Showing the first eight; more decompositions exist.
