Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545532, here are decompositions:
- 131 + 31545401 = 31545532
- 233 + 31545299 = 31545532
- 311 + 31545221 = 31545532
- 449 + 31545083 = 31545532
- 509 + 31545023 = 31545532
- 563 + 31544969 = 31545532
- 569 + 31544963 = 31545532
- 653 + 31544879 = 31545532
Showing the first eight; more decompositions exist.
