Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542440, here are decompositions:
- 3 + 31542437 = 31542440
- 43 + 31542397 = 31542440
- 67 + 31542373 = 31542440
- 211 + 31542229 = 31542440
- 277 + 31542163 = 31542440
- 337 + 31542103 = 31542440
- 373 + 31542067 = 31542440
- 409 + 31542031 = 31542440
Showing the first eight; more decompositions exist.
