Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724126, here are decompositions:

53 + 8724073 = 8724126
113 + 8724013 = 8724126
139 + 8723987 = 8724126
149 + 8723977 = 8724126
179 + 8723947 = 8724126
193 + 8723933 = 8724126
197 + 8723929 = 8724126
223 + 8723903 = 8724126

Showing the first eight; more decompositions exist.
