Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8692388, here are decompositions:

37 + 8692351 = 8692388
79 + 8692309 = 8692388
109 + 8692279 = 8692388
139 + 8692249 = 8692388
151 + 8692237 = 8692388
181 + 8692207 = 8692388
337 + 8692051 = 8692388
409 + 8691979 = 8692388

Showing the first eight; more decompositions exist.
