Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650478, here are decompositions:

19 + 8650459 = 8650478
157 + 8650321 = 8650478
337 + 8650141 = 8650478
349 + 8650129 = 8650478
439 + 8650039 = 8650478
541 + 8649937 = 8650478
607 + 8649871 = 8650478
631 + 8649847 = 8650478

Showing the first eight; more decompositions exist.
