Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87330, here are decompositions:
- 7 + 87323 = 87330
- 13 + 87317 = 87330
- 17 + 87313 = 87330
- 31 + 87299 = 87330
- 37 + 87293 = 87330
- 53 + 87277 = 87330
- 73 + 87257 = 87330
- 79 + 87251 = 87330
Showing the first eight; more decompositions exist.
