Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102718, here are decompositions:
- 17 + 102701 = 102718
- 41 + 102677 = 102718
- 71 + 102647 = 102718
- 107 + 102611 = 102718
- 131 + 102587 = 102718
- 167 + 102551 = 102718
- 179 + 102539 = 102718
- 257 + 102461 = 102718
Showing the first eight; more decompositions exist.
