Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540064, here are decompositions:
- 97 + 31539967 = 31540064
- 163 + 31539901 = 31540064
- 307 + 31539757 = 31540064
- 337 + 31539727 = 31540064
- 421 + 31539643 = 31540064
- 541 + 31539523 = 31540064
- 643 + 31539421 = 31540064
- 727 + 31539337 = 31540064
Showing the first eight; more decompositions exist.
