Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526428, here are decompositions:
- 5 + 31526423 = 31526428
- 41 + 31526387 = 31526428
- 239 + 31526189 = 31526428
- 359 + 31526069 = 31526428
- 509 + 31525919 = 31526428
- 587 + 31525841 = 31526428
- 617 + 31525811 = 31526428
- 641 + 31525787 = 31526428
Showing the first eight; more decompositions exist.
