Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501052, here are decompositions:

13 + 31501039 = 31501052
43 + 31501009 = 31501052
73 + 31500979 = 31501052
181 + 31500871 = 31501052
199 + 31500853 = 31501052
463 + 31500589 = 31501052
523 + 31500529 = 31501052
601 + 31500451 = 31501052

Showing the first eight; more decompositions exist.
