Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103688, here are decompositions:
- 7 + 103681 = 103688
- 19 + 103669 = 103688
- 31 + 103657 = 103688
- 37 + 103651 = 103688
- 97 + 103591 = 103688
- 127 + 103561 = 103688
- 139 + 103549 = 103688
- 331 + 103357 = 103688
Showing the first eight; more decompositions exist.
