Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739156, here are decompositions:

29 + 8739127 = 8739156
37 + 8739119 = 8739156
43 + 8739113 = 8739156
59 + 8739097 = 8739156
103 + 8739053 = 8739156
149 + 8739007 = 8739156
193 + 8738963 = 8739156
199 + 8738957 = 8739156

Showing the first eight; more decompositions exist.
