Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501670, here are decompositions:

37 + 31501633 = 31501670
103 + 31501567 = 31501670
139 + 31501531 = 31501670
223 + 31501447 = 31501670
271 + 31501399 = 31501670
283 + 31501387 = 31501670
337 + 31501333 = 31501670
349 + 31501321 = 31501670

Showing the first eight; more decompositions exist.
