Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723002, here are decompositions:

3 + 8722999 = 8723002
11 + 8722991 = 8723002
53 + 8722949 = 8723002
89 + 8722913 = 8723002
173 + 8722829 = 8723002
263 + 8722739 = 8723002
359 + 8722643 = 8723002
389 + 8722613 = 8723002

Showing the first eight; more decompositions exist.
