Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737778, here are decompositions:

37 + 8737741 = 8737778
61 + 8737717 = 8737778
79 + 8737699 = 8737778
109 + 8737669 = 8737778
151 + 8737627 = 8737778
277 + 8737501 = 8737778
421 + 8737357 = 8737778
541 + 8737237 = 8737778

Showing the first eight; more decompositions exist.
