Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749930, here are decompositions:

3 + 8749927 = 8749930
83 + 8749847 = 8749930
89 + 8749841 = 8749930
113 + 8749817 = 8749930
179 + 8749751 = 8749930
197 + 8749733 = 8749930
317 + 8749613 = 8749930
359 + 8749571 = 8749930

Showing the first eight; more decompositions exist.
