Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667172, here are decompositions:

5 + 8667167 = 8667172
179 + 8666993 = 8667172
233 + 8666939 = 8667172
281 + 8666891 = 8667172
389 + 8666783 = 8667172
461 + 8666711 = 8667172
491 + 8666681 = 8667172
653 + 8666519 = 8667172

Showing the first eight; more decompositions exist.
