Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526578, here are decompositions:
- 89 + 31526489 = 31526578
- 101 + 31526477 = 31526578
- 191 + 31526387 = 31526578
- 227 + 31526351 = 31526578
- 389 + 31526189 = 31526578
- 491 + 31526087 = 31526578
- 509 + 31526069 = 31526578
- 521 + 31526057 = 31526578
Showing the first eight; more decompositions exist.
