Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678120, here are decompositions:

7 + 8678113 = 8678120
37 + 8678083 = 8678120
67 + 8678053 = 8678120
109 + 8678011 = 8678120
127 + 8677993 = 8678120
229 + 8677891 = 8678120
349 + 8677771 = 8678120
397 + 8677723 = 8678120

Showing the first eight; more decompositions exist.
