Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540234, here are decompositions:
- 17 + 31540217 = 31540234
- 23 + 31540211 = 31540234
- 53 + 31540181 = 31540234
- 71 + 31540163 = 31540234
- 227 + 31540007 = 31540234
- 263 + 31539971 = 31540234
- 521 + 31539713 = 31540234
- 563 + 31539671 = 31540234
Showing the first eight; more decompositions exist.
