Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501936, here are decompositions:

23 + 31501913 = 31501936
29 + 31501907 = 31501936
113 + 31501823 = 31501936
317 + 31501619 = 31501936
353 + 31501583 = 31501936
503 + 31501433 = 31501936
509 + 31501427 = 31501936
1013 + 31500923 = 31501936

Showing the first eight; more decompositions exist.
