Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522936, here are decompositions:

47 + 31522889 = 31522936
89 + 31522847 = 31522936
113 + 31522823 = 31522936
353 + 31522583 = 31522936
383 + 31522553 = 31522936
443 + 31522493 = 31522936
503 + 31522433 = 31522936
563 + 31522373 = 31522936

Showing the first eight; more decompositions exist.
