Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740388, here are decompositions:

61 + 8740327 = 8740388
67 + 8740321 = 8740388
271 + 8740117 = 8740388
277 + 8740111 = 8740388
421 + 8739967 = 8740388
487 + 8739901 = 8740388
577 + 8739811 = 8740388
619 + 8739769 = 8740388

Showing the first eight; more decompositions exist.
