Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678072, here are decompositions:

3 + 8678069 = 8678072
19 + 8678053 = 8678072
43 + 8678029 = 8678072
61 + 8678011 = 8678072
79 + 8677993 = 8678072
181 + 8677891 = 8678072
313 + 8677759 = 8678072
349 + 8677723 = 8678072

Showing the first eight; more decompositions exist.
