Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655158, here are decompositions:

151 + 8655007 = 8655158
199 + 8654959 = 8655158
241 + 8654917 = 8655158
349 + 8654809 = 8655158
397 + 8654761 = 8655158
409 + 8654749 = 8655158
541 + 8654617 = 8655158
691 + 8654467 = 8655158

Showing the first eight; more decompositions exist.
