Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655478, here are decompositions:

107 + 8655371 = 8655478
191 + 8655287 = 8655478
281 + 8655197 = 8655478
311 + 8655167 = 8655478
431 + 8655047 = 8655478
449 + 8655029 = 8655478
467 + 8655011 = 8655478
641 + 8654837 = 8655478

Showing the first eight; more decompositions exist.
