Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526272, here are decompositions:
- 59 + 31526213 = 31526272
- 83 + 31526189 = 31526272
- 131 + 31526141 = 31526272
- 251 + 31526021 = 31526272
- 353 + 31525919 = 31526272
- 359 + 31525913 = 31526272
- 383 + 31525889 = 31526272
- 431 + 31525841 = 31526272
Showing the first eight; more decompositions exist.
