Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542292, here are decompositions:
- 11 + 31542281 = 31542292
- 59 + 31542233 = 31542292
- 179 + 31542113 = 31542292
- 269 + 31542023 = 31542292
- 281 + 31542011 = 31542292
- 311 + 31541981 = 31542292
- 359 + 31541933 = 31542292
- 389 + 31541903 = 31542292
Showing the first eight; more decompositions exist.
