Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502582, here are decompositions:

19 + 31502563 = 31502582
43 + 31502539 = 31502582
151 + 31502431 = 31502582
211 + 31502371 = 31502582
229 + 31502353 = 31502582
271 + 31502311 = 31502582
313 + 31502269 = 31502582
421 + 31502161 = 31502582

Showing the first eight; more decompositions exist.
