Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712940, here are decompositions:

113 + 8712827 = 8712940
179 + 8712761 = 8712940
191 + 8712749 = 8712940
227 + 8712713 = 8712940
239 + 8712701 = 8712940
263 + 8712677 = 8712940
311 + 8712629 = 8712940
443 + 8712497 = 8712940

Showing the first eight; more decompositions exist.
