Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655538, here are decompositions:

11 + 8655527 = 8655538
41 + 8655497 = 8655538
137 + 8655401 = 8655538
167 + 8655371 = 8655538
251 + 8655287 = 8655538
389 + 8655149 = 8655538
467 + 8655071 = 8655538
491 + 8655047 = 8655538

Showing the first eight; more decompositions exist.
