Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526188, here are decompositions:
- 47 + 31526141 = 31526188
- 101 + 31526087 = 31526188
- 131 + 31526057 = 31526188
- 137 + 31526051 = 31526188
- 167 + 31526021 = 31526188
- 269 + 31525919 = 31526188
- 347 + 31525841 = 31526188
- 389 + 31525799 = 31526188
Showing the first eight; more decompositions exist.
