Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502152, here are decompositions:

5 + 31502147 = 31502152
23 + 31502129 = 31502152
53 + 31502099 = 31502152
173 + 31501979 = 31502152
239 + 31501913 = 31502152
401 + 31501751 = 31502152
431 + 31501721 = 31502152
491 + 31501661 = 31502152

Showing the first eight; more decompositions exist.
