Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87918, here are decompositions:
- 7 + 87911 = 87918
- 31 + 87887 = 87918
- 37 + 87881 = 87918
- 41 + 87877 = 87918
- 107 + 87811 = 87918
- 151 + 87767 = 87918
- 167 + 87751 = 87918
- 179 + 87739 = 87918
Showing the first eight; more decompositions exist.
