Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87264, here are decompositions:
- 7 + 87257 = 87264
- 11 + 87253 = 87264
- 13 + 87251 = 87264
- 41 + 87223 = 87264
- 43 + 87221 = 87264
- 53 + 87211 = 87264
- 83 + 87181 = 87264
- 113 + 87151 = 87264
Showing the first eight; more decompositions exist.
