Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737478, here are decompositions:

19 + 8737459 = 8737478
229 + 8737249 = 8737478
241 + 8737237 = 8737478
349 + 8737129 = 8737478
367 + 8737111 = 8737478
439 + 8737039 = 8737478
457 + 8737021 = 8737478
571 + 8736907 = 8737478

Showing the first eight; more decompositions exist.
