Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502370, here are decompositions:

7 + 31502363 = 31502370
17 + 31502353 = 31502370
37 + 31502333 = 31502370
41 + 31502329 = 31502370
59 + 31502311 = 31502370
83 + 31502287 = 31502370
101 + 31502269 = 31502370
127 + 31502243 = 31502370

Showing the first eight; more decompositions exist.
