Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737388, here are decompositions:

31 + 8737357 = 8737388
139 + 8737249 = 8737388
151 + 8737237 = 8737388
211 + 8737177 = 8737388
271 + 8737117 = 8737388
277 + 8737111 = 8737388
349 + 8737039 = 8737388
367 + 8737021 = 8737388

Showing the first eight; more decompositions exist.
