Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712972, here are decompositions:

41 + 8712931 = 8712972
53 + 8712919 = 8712972
109 + 8712863 = 8712972
113 + 8712859 = 8712972
179 + 8712793 = 8712972
193 + 8712779 = 8712972
211 + 8712761 = 8712972
223 + 8712749 = 8712972

Showing the first eight; more decompositions exist.
