Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739130, here are decompositions:

3 + 8739127 = 8739130
11 + 8739119 = 8739130
17 + 8739113 = 8739130
107 + 8739023 = 8739130
167 + 8738963 = 8739130
173 + 8738957 = 8739130
293 + 8738837 = 8739130
317 + 8738813 = 8739130

Showing the first eight; more decompositions exist.
