Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540962, here are decompositions:
- 23 + 31540939 = 31540962
- 41 + 31540921 = 31540962
- 139 + 31540823 = 31540962
- 149 + 31540813 = 31540962
- 179 + 31540783 = 31540962
- 239 + 31540723 = 31540962
- 263 + 31540699 = 31540962
- 269 + 31540693 = 31540962
Showing the first eight; more decompositions exist.
