Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501752, here are decompositions:

11 + 31501741 = 31501752
31 + 31501721 = 31501752
53 + 31501699 = 31501752
83 + 31501669 = 31501752
131 + 31501621 = 31501752
229 + 31501523 = 31501752
349 + 31501403 = 31501752
353 + 31501399 = 31501752

Showing the first eight; more decompositions exist.
