Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540626, here are decompositions:
- 53 + 31540573 = 31540626
- 97 + 31540529 = 31540626
- 127 + 31540499 = 31540626
- 137 + 31540489 = 31540626
- 263 + 31540363 = 31540626
- 283 + 31540343 = 31540626
- 317 + 31540309 = 31540626
- 409 + 31540217 = 31540626
Showing the first eight; more decompositions exist.
