Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724256, here are decompositions:

3 + 8724253 = 8724256
113 + 8724143 = 8724256
263 + 8723993 = 8724256
269 + 8723987 = 8724256
347 + 8723909 = 8724256
353 + 8723903 = 8724256
449 + 8723807 = 8724256
467 + 8723789 = 8724256

Showing the first eight; more decompositions exist.
