Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502084, here are decompositions:

127 + 31501957 = 31502084
223 + 31501861 = 31502084
277 + 31501807 = 31502084
463 + 31501621 = 31502084
547 + 31501537 = 31502084
751 + 31501333 = 31502084
853 + 31501231 = 31502084
883 + 31501201 = 31502084

Showing the first eight; more decompositions exist.
