Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543272, here are decompositions:
- 29 + 31543243 = 31543272
- 41 + 31543231 = 31543272
- 53 + 31543219 = 31543272
- 109 + 31543163 = 31543272
- 139 + 31543133 = 31543272
- 193 + 31543079 = 31543272
- 263 + 31543009 = 31543272
- 281 + 31542991 = 31543272
Showing the first eight; more decompositions exist.
