Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87258, here are decompositions:
- 5 + 87253 = 87258
- 7 + 87251 = 87258
- 37 + 87221 = 87258
- 47 + 87211 = 87258
- 71 + 87187 = 87258
- 79 + 87179 = 87258
- 107 + 87151 = 87258
- 109 + 87149 = 87258
Showing the first eight; more decompositions exist.
