Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532954, here are decompositions:
- 31 + 31532923 = 31532954
- 73 + 31532881 = 31532954
- 367 + 31532587 = 31532954
- 373 + 31532581 = 31532954
- 433 + 31532521 = 31532954
- 457 + 31532497 = 31532954
- 601 + 31532353 = 31532954
- 613 + 31532341 = 31532954
Showing the first eight; more decompositions exist.
