Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538496, here are decompositions:
- 5 + 31538491 = 31538496
- 7 + 31538489 = 31538496
- 19 + 31538477 = 31538496
- 23 + 31538473 = 31538496
- 47 + 31538449 = 31538496
- 53 + 31538443 = 31538496
- 89 + 31538407 = 31538496
- 163 + 31538333 = 31538496
Showing the first eight; more decompositions exist.
