Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526542, here are decompositions:
- 53 + 31526489 = 31526542
- 191 + 31526351 = 31526542
- 269 + 31526273 = 31526542
- 353 + 31526189 = 31526542
- 401 + 31526141 = 31526542
- 479 + 31526063 = 31526542
- 491 + 31526051 = 31526542
- 521 + 31526021 = 31526542
Showing the first eight; more decompositions exist.
