Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502082, here are decompositions:

103 + 31501979 = 31502082
233 + 31501849 = 31502082
251 + 31501831 = 31502082
263 + 31501819 = 31502082
331 + 31501751 = 31502082
383 + 31501699 = 31502082
421 + 31501661 = 31502082
449 + 31501633 = 31502082

Showing the first eight; more decompositions exist.
