Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502528, here are decompositions:

97 + 31502431 = 31502528
157 + 31502371 = 31502528
199 + 31502329 = 31502528
241 + 31502287 = 31502528
367 + 31502161 = 31502528
397 + 31502131 = 31502528
571 + 31501957 = 31502528
709 + 31501819 = 31502528

Showing the first eight; more decompositions exist.
