Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693228, here are decompositions:

31 + 8693197 = 8693228
67 + 8693161 = 8693228
97 + 8693131 = 8693228
157 + 8693071 = 8693228
241 + 8692987 = 8693228
409 + 8692819 = 8693228
421 + 8692807 = 8693228
541 + 8692687 = 8693228

Showing the first eight; more decompositions exist.
