Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526572, here are decompositions:
- 83 + 31526489 = 31526572
- 149 + 31526423 = 31526572
- 359 + 31526213 = 31526572
- 383 + 31526189 = 31526572
- 431 + 31526141 = 31526572
- 503 + 31526069 = 31526572
- 509 + 31526063 = 31526572
- 521 + 31526051 = 31526572
Showing the first eight; more decompositions exist.
