Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725732, here are decompositions:

89 + 8725643 = 8725732
101 + 8725631 = 8725732
233 + 8725499 = 8725732
251 + 8725481 = 8725732
269 + 8725463 = 8725732
311 + 8725421 = 8725732
479 + 8725253 = 8725732
593 + 8725139 = 8725732

Showing the first eight; more decompositions exist.
