Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480936, here are decompositions:

17 + 31480919 = 31480936
23 + 31480913 = 31480936
107 + 31480829 = 31480936
167 + 31480769 = 31480936
173 + 31480763 = 31480936
503 + 31480433 = 31480936
563 + 31480373 = 31480936
569 + 31480367 = 31480936

Showing the first eight; more decompositions exist.
