Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612042, here are decompositions:

3 + 8612039 = 8612042
31 + 8612011 = 8612042
73 + 8611969 = 8612042
139 + 8611903 = 8612042
151 + 8611891 = 8612042
163 + 8611879 = 8612042
193 + 8611849 = 8612042
223 + 8611819 = 8612042

Showing the first eight; more decompositions exist.
