Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504492, here are decompositions:

11 + 31504481 = 31504492
53 + 31504439 = 31504492
263 + 31504229 = 31504492
359 + 31504133 = 31504492
389 + 31504103 = 31504492
479 + 31504013 = 31504492
521 + 31503971 = 31504492
563 + 31503929 = 31504492

Showing the first eight; more decompositions exist.
