Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733778, here are decompositions:

41 + 8733737 = 8733778
47 + 8733731 = 8733778
59 + 8733719 = 8733778
71 + 8733707 = 8733778
101 + 8733677 = 8733778
227 + 8733551 = 8733778
311 + 8733467 = 8733778
359 + 8733419 = 8733778

Showing the first eight; more decompositions exist.
