Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725012, here are decompositions:

29 + 8724983 = 8725012
83 + 8724929 = 8725012
293 + 8724719 = 8725012
641 + 8724371 = 8725012
683 + 8724329 = 8725012
701 + 8724311 = 8725012
719 + 8724293 = 8725012
743 + 8724269 = 8725012

Showing the first eight; more decompositions exist.
