Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612178, here are decompositions:

11 + 8612167 = 8612178
59 + 8612119 = 8612178
79 + 8612099 = 8612178
89 + 8612089 = 8612178
139 + 8612039 = 8612178
167 + 8612011 = 8612178
191 + 8611987 = 8612178
331 + 8611847 = 8612178

Showing the first eight; more decompositions exist.
