Goldbach decomposition

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.
