Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501064, here are decompositions:

3 + 31501061 = 31501064
97 + 31500967 = 31501064
193 + 31500871 = 31501064
211 + 31500853 = 31501064
271 + 31500793 = 31501064
373 + 31500691 = 31501064
577 + 31500487 = 31501064
601 + 31500463 = 31501064

Showing the first eight; more decompositions exist.
