Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87318, here are decompositions:
- 5 + 87313 = 87318
- 19 + 87299 = 87318
- 37 + 87281 = 87318
- 41 + 87277 = 87318
- 61 + 87257 = 87318
- 67 + 87251 = 87318
- 97 + 87221 = 87318
- 107 + 87211 = 87318
Showing the first eight; more decompositions exist.
