Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501652, here are decompositions:

19 + 31501633 = 31501652
31 + 31501621 = 31501652
331 + 31501321 = 31501652
349 + 31501303 = 31501652
421 + 31501231 = 31501652
433 + 31501219 = 31501652
571 + 31501081 = 31501652
613 + 31501039 = 31501652

Showing the first eight; more decompositions exist.
