Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501034, here are decompositions:

67 + 31500967 = 31501034
163 + 31500871 = 31501034
181 + 31500853 = 31501034
241 + 31500793 = 31501034
547 + 31500487 = 31501034
571 + 31500463 = 31501034
577 + 31500457 = 31501034
673 + 31500361 = 31501034

Showing the first eight; more decompositions exist.
