Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87286, here are decompositions:
- 5 + 87281 = 87286
- 29 + 87257 = 87286
- 107 + 87179 = 87286
- 137 + 87149 = 87286
- 167 + 87119 = 87286
- 179 + 87107 = 87286
- 293 + 86993 = 87286
- 317 + 86969 = 87286
Showing the first eight; more decompositions exist.
