Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18098, here are decompositions:
- 37 + 18061 = 18098
- 109 + 17989 = 18098
- 127 + 17971 = 18098
- 139 + 17959 = 18098
- 271 + 17827 = 18098
- 307 + 17791 = 18098
- 337 + 17761 = 18098
- 349 + 17749 = 18098
Showing the first eight; more decompositions exist.
