Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87038, here are decompositions:

79 + 86959 = 87038
109 + 86929 = 87038
181 + 86857 = 87038
271 + 86767 = 87038
349 + 86689 = 87038
409 + 86629 = 87038
439 + 86599 = 87038
499 + 86539 = 87038

Showing the first eight; more decompositions exist.
