Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1272, here are decompositions:
- 13 + 1259 = 1272
- 23 + 1249 = 1272
- 41 + 1231 = 1272
- 43 + 1229 = 1272
- 59 + 1213 = 1272
- 71 + 1201 = 1272
- 79 + 1193 = 1272
- 101 + 1171 = 1272
Showing the first eight; more decompositions exist.
