Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737148, here are decompositions:

19 + 8737129 = 8737148
31 + 8737117 = 8737148
37 + 8737111 = 8737148
109 + 8737039 = 8737148
127 + 8737021 = 8737148
229 + 8736919 = 8737148
241 + 8736907 = 8737148
331 + 8736817 = 8737148

Showing the first eight; more decompositions exist.
