Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562936, here are decompositions:

19 + 31562917 = 31562936
109 + 31562827 = 31562936
157 + 31562779 = 31562936
199 + 31562737 = 31562936
313 + 31562623 = 31562936
487 + 31562449 = 31562936
547 + 31562389 = 31562936
607 + 31562329 = 31562936

Showing the first eight; more decompositions exist.
