Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13282, here are decompositions:
- 23 + 13259 = 13282
- 41 + 13241 = 13282
- 53 + 13229 = 13282
- 131 + 13151 = 13282
- 173 + 13109 = 13282
- 179 + 13103 = 13282
- 233 + 13049 = 13282
- 239 + 13043 = 13282
Showing the first eight; more decompositions exist.
