Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502002, here are decompositions:

23 + 31501979 = 31502002
89 + 31501913 = 31502002
179 + 31501823 = 31502002
251 + 31501751 = 31502002
281 + 31501721 = 31502002
383 + 31501619 = 31502002
419 + 31501583 = 31502002
479 + 31501523 = 31502002

Showing the first eight; more decompositions exist.
