Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532802, here are decompositions:
- 53 + 31532749 = 31532802
- 109 + 31532693 = 31532802
- 149 + 31532653 = 31532802
- 163 + 31532639 = 31532802
- 229 + 31532573 = 31532802
- 251 + 31532551 = 31532802
- 263 + 31532539 = 31532802
- 281 + 31532521 = 31532802
Showing the first eight; more decompositions exist.
