Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87270, here are decompositions:
- 13 + 87257 = 87270
- 17 + 87253 = 87270
- 19 + 87251 = 87270
- 47 + 87223 = 87270
- 59 + 87211 = 87270
- 83 + 87187 = 87270
- 89 + 87181 = 87270
- 137 + 87133 = 87270
Showing the first eight; more decompositions exist.
