Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650142, here are decompositions:

13 + 8650129 = 8650142
19 + 8650123 = 8650142
103 + 8650039 = 8650142
139 + 8650003 = 8650142
271 + 8649871 = 8650142
349 + 8649793 = 8650142
379 + 8649763 = 8650142
421 + 8649721 = 8650142

Showing the first eight; more decompositions exist.
