Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739136, here are decompositions:

17 + 8739119 = 8739136
23 + 8739113 = 8739136
83 + 8739053 = 8739136
113 + 8739023 = 8739136
173 + 8738963 = 8739136
179 + 8738957 = 8739136
293 + 8738843 = 8739136
353 + 8738783 = 8739136

Showing the first eight; more decompositions exist.
