Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537966, here are decompositions:

107 + 31537859 = 31537966
419 + 31537547 = 31537966
557 + 31537409 = 31537966
653 + 31537313 = 31537966
659 + 31537307 = 31537966
743 + 31537223 = 31537966
839 + 31537127 = 31537966
983 + 31536983 = 31537966

Showing the first eight; more decompositions exist.
