Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526130, here are decompositions:
- 43 + 31526087 = 31526130
- 47 + 31526083 = 31526130
- 61 + 31526069 = 31526130
- 67 + 31526063 = 31526130
- 73 + 31526057 = 31526130
- 79 + 31526051 = 31526130
- 109 + 31526021 = 31526130
- 149 + 31525981 = 31526130
Showing the first eight; more decompositions exist.
