Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526518, here are decompositions:
- 29 + 31526489 = 31526518
- 41 + 31526477 = 31526518
- 131 + 31526387 = 31526518
- 167 + 31526351 = 31526518
- 311 + 31526207 = 31526518
- 431 + 31526087 = 31526518
- 449 + 31526069 = 31526518
- 461 + 31526057 = 31526518
Showing the first eight; more decompositions exist.
