Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726120, here are decompositions:

19 + 8726101 = 8726120
103 + 8726017 = 8726120
157 + 8725963 = 8726120
307 + 8725813 = 8726120
421 + 8725699 = 8726120
439 + 8725681 = 8726120
463 + 8725657 = 8726120
499 + 8725621 = 8726120

Showing the first eight; more decompositions exist.
