Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502468, here are decompositions:

37 + 31502431 = 31502468
97 + 31502371 = 31502468
139 + 31502329 = 31502468
157 + 31502311 = 31502468
181 + 31502287 = 31502468
199 + 31502269 = 31502468
307 + 31502161 = 31502468
337 + 31502131 = 31502468

Showing the first eight; more decompositions exist.
