Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526864, here are decompositions:
- 73 + 31526791 = 31526864
- 151 + 31526713 = 31526864
- 331 + 31526533 = 31526864
- 337 + 31526527 = 31526864
- 367 + 31526497 = 31526864
- 433 + 31526431 = 31526864
- 547 + 31526317 = 31526864
- 643 + 31526221 = 31526864
Showing the first eight; more decompositions exist.
