Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739228, here are decompositions:

19 + 8739209 = 8739228
31 + 8739197 = 8739228
41 + 8739187 = 8739228
59 + 8739169 = 8739228
61 + 8739167 = 8739228
101 + 8739127 = 8739228
109 + 8739119 = 8739228
131 + 8739097 = 8739228

Showing the first eight; more decompositions exist.
