Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540598, here are decompositions:
- 97 + 31540501 = 31540598
- 109 + 31540489 = 31540598
- 127 + 31540471 = 31540598
- 157 + 31540441 = 31540598
- 181 + 31540417 = 31540598
- 337 + 31540261 = 31540598
- 409 + 31540189 = 31540598
- 499 + 31540099 = 31540598
Showing the first eight; more decompositions exist.
