Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87508, here are decompositions:
- 17 + 87491 = 87508
- 101 + 87407 = 87508
- 149 + 87359 = 87508
- 191 + 87317 = 87508
- 227 + 87281 = 87508
- 251 + 87257 = 87508
- 257 + 87251 = 87508
- 359 + 87149 = 87508
Showing the first eight; more decompositions exist.
