Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737238, here are decompositions:

61 + 8737177 = 8737238
109 + 8737129 = 8737238
127 + 8737111 = 8737238
199 + 8737039 = 8737238
331 + 8736907 = 8737238
421 + 8736817 = 8737238
439 + 8736799 = 8737238
457 + 8736781 = 8737238

Showing the first eight; more decompositions exist.
