Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504372, here are decompositions:

5 + 31504367 = 31504372
239 + 31504133 = 31504372
269 + 31504103 = 31504372
359 + 31504013 = 31504372
401 + 31503971 = 31504372
443 + 31503929 = 31504372
461 + 31503911 = 31504372
509 + 31503863 = 31504372

Showing the first eight; more decompositions exist.
