Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528936, here are decompositions:

83 + 31528853 = 31528936
113 + 31528823 = 31528936
239 + 31528697 = 31528936
389 + 31528547 = 31528936
503 + 31528433 = 31528936
563 + 31528373 = 31528936
587 + 31528349 = 31528936
599 + 31528337 = 31528936

Showing the first eight; more decompositions exist.
