Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38618, here are decompositions:

7 + 38611 = 38618
61 + 38557 = 38618
157 + 38461 = 38618
241 + 38377 = 38618
331 + 38287 = 38618
337 + 38281 = 38618
379 + 38239 = 38618
421 + 38197 = 38618

Showing the first eight; more decompositions exist.
