Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544536, here are decompositions:

3 + 31544533 = 31544536
5 + 31544531 = 31544536
173 + 31544363 = 31544536
239 + 31544297 = 31544536
347 + 31544189 = 31544536
383 + 31544153 = 31544536
479 + 31544057 = 31544536
503 + 31544033 = 31544536

Showing the first eight; more decompositions exist.
