Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725930, here are decompositions:

53 + 8725877 = 8725930
89 + 8725841 = 8725930
107 + 8725823 = 8725930
113 + 8725817 = 8725930
131 + 8725799 = 8725930
173 + 8725757 = 8725930
197 + 8725733 = 8725930
359 + 8725571 = 8725930

Showing the first eight; more decompositions exist.
