Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750146, here are decompositions:

23 + 8750123 = 8750146
107 + 8750039 = 8750146
113 + 8750033 = 8750146
359 + 8749787 = 8750146
557 + 8749589 = 8750146
677 + 8749469 = 8750146
809 + 8749337 = 8750146
947 + 8749199 = 8750146

Showing the first eight; more decompositions exist.
