Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713228, here are decompositions:

11 + 8713217 = 8713228
47 + 8713181 = 8713228
71 + 8713157 = 8713228
101 + 8713127 = 8713228
107 + 8713121 = 8713228
191 + 8713037 = 8713228
401 + 8712827 = 8713228
449 + 8712779 = 8713228

Showing the first eight; more decompositions exist.
