Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531926, here are decompositions:
- 5 + 31531921 = 31531926
- 17 + 31531909 = 31531926
- 43 + 31531883 = 31531926
- 109 + 31531817 = 31531926
- 113 + 31531813 = 31531926
- 199 + 31531727 = 31531926
- 277 + 31531649 = 31531926
- 347 + 31531579 = 31531926
Showing the first eight; more decompositions exist.
