Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725972, here are decompositions:

11 + 8725961 = 8725972
23 + 8725949 = 8725972
41 + 8725931 = 8725972
131 + 8725841 = 8725972
149 + 8725823 = 8725972
173 + 8725799 = 8725972
239 + 8725733 = 8725972
401 + 8725571 = 8725972

Showing the first eight; more decompositions exist.
