Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750042, here are decompositions:

3 + 8750039 = 8750042
31 + 8750011 = 8750042
61 + 8749981 = 8750042
139 + 8749903 = 8750042
151 + 8749891 = 8750042
229 + 8749813 = 8750042
271 + 8749771 = 8750042
373 + 8749669 = 8750042

Showing the first eight; more decompositions exist.
