Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502604, here are decompositions:

17 + 31502587 = 31502604
41 + 31502563 = 31502604
43 + 31502561 = 31502604
47 + 31502557 = 31502604
71 + 31502533 = 31502604
163 + 31502441 = 31502604
173 + 31502431 = 31502604
233 + 31502371 = 31502604

Showing the first eight; more decompositions exist.
