Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655588, here are decompositions:

61 + 8655527 = 8655588
131 + 8655457 = 8655588
167 + 8655421 = 8655588
239 + 8655349 = 8655588
257 + 8655331 = 8655588
281 + 8655307 = 8655588
421 + 8655167 = 8655588
439 + 8655149 = 8655588

Showing the first eight; more decompositions exist.
