Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539352, here are decompositions:
- 3 + 31539349 = 31539352
- 23 + 31539329 = 31539352
- 263 + 31539089 = 31539352
- 269 + 31539083 = 31539352
- 401 + 31538951 = 31539352
- 563 + 31538789 = 31539352
- 599 + 31538753 = 31539352
- 641 + 31538711 = 31539352
Showing the first eight; more decompositions exist.
