Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750142, here are decompositions:

19 + 8750123 = 8750142
41 + 8750101 = 8750142
73 + 8750069 = 8750142
103 + 8750039 = 8750142
109 + 8750033 = 8750142
131 + 8750011 = 8750142
151 + 8749991 = 8750142
239 + 8749903 = 8750142

Showing the first eight; more decompositions exist.
