Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540052, here are decompositions:
- 43 + 31540009 = 31540052
- 151 + 31539901 = 31540052
- 163 + 31539889 = 31540052
- 409 + 31539643 = 31540052
- 613 + 31539439 = 31540052
- 631 + 31539421 = 31540052
- 769 + 31539283 = 31540052
- 811 + 31539241 = 31540052
Showing the first eight; more decompositions exist.
