Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502376, here are decompositions:

5 + 31502371 = 31502376
13 + 31502363 = 31502376
23 + 31502353 = 31502376
43 + 31502333 = 31502376
47 + 31502329 = 31502376
89 + 31502287 = 31502376
97 + 31502279 = 31502376
107 + 31502269 = 31502376

Showing the first eight; more decompositions exist.
