Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739230, here are decompositions:

37 + 8739193 = 8739230
43 + 8739187 = 8739230
61 + 8739169 = 8739230
67 + 8739163 = 8739230
103 + 8739127 = 8739230
151 + 8739079 = 8739230
223 + 8739007 = 8739230
229 + 8739001 = 8739230

Showing the first eight; more decompositions exist.
