Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542196, here are decompositions:
- 47 + 31542149 = 31542196
- 83 + 31542113 = 31542196
- 113 + 31542083 = 31542196
- 173 + 31542023 = 31542196
- 263 + 31541933 = 31542196
- 293 + 31541903 = 31542196
- 503 + 31541693 = 31542196
- 563 + 31541633 = 31542196
Showing the first eight; more decompositions exist.
