Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655340, here are decompositions:

53 + 8655287 = 8655340
167 + 8655173 = 8655340
173 + 8655167 = 8655340
191 + 8655149 = 8655340
269 + 8655071 = 8655340
293 + 8655047 = 8655340
311 + 8655029 = 8655340
359 + 8654981 = 8655340

Showing the first eight; more decompositions exist.
