Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502600, here are decompositions:

13 + 31502587 = 31502600
37 + 31502563 = 31502600
43 + 31502557 = 31502600
61 + 31502539 = 31502600
67 + 31502533 = 31502600
229 + 31502371 = 31502600
271 + 31502329 = 31502600
313 + 31502287 = 31502600

Showing the first eight; more decompositions exist.
