Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738872, here are decompositions:

29 + 8738843 = 8738872
59 + 8738813 = 8738872
71 + 8738801 = 8738872
89 + 8738783 = 8738872
113 + 8738759 = 8738872
281 + 8738591 = 8738872
293 + 8738579 = 8738872
509 + 8738363 = 8738872

Showing the first eight; more decompositions exist.
