Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723698, here are decompositions:

59 + 8723639 = 8723698
89 + 8723609 = 8723698
167 + 8723531 = 8723698
239 + 8723459 = 8723698
257 + 8723441 = 8723698
311 + 8723387 = 8723698
617 + 8723081 = 8723698
821 + 8722877 = 8723698

Showing the first eight; more decompositions exist.
