Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502382, here are decompositions:

11 + 31502371 = 31502382
19 + 31502363 = 31502382
29 + 31502353 = 31502382
53 + 31502329 = 31502382
71 + 31502311 = 31502382
103 + 31502279 = 31502382
113 + 31502269 = 31502382
139 + 31502243 = 31502382

Showing the first eight; more decompositions exist.
