Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739164, here are decompositions:

37 + 8739127 = 8739164
67 + 8739097 = 8739164
157 + 8739007 = 8739164
163 + 8739001 = 8739164
283 + 8738881 = 8739164
397 + 8738767 = 8739164
457 + 8738707 = 8739164
523 + 8738641 = 8739164

Showing the first eight; more decompositions exist.
