Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87358, here are decompositions:
- 41 + 87317 = 87358
- 59 + 87299 = 87358
- 101 + 87257 = 87358
- 107 + 87251 = 87358
- 137 + 87221 = 87358
- 179 + 87179 = 87358
- 239 + 87119 = 87358
- 251 + 87107 = 87358
Showing the first eight; more decompositions exist.
