Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504414, here are decompositions:

41 + 31504373 = 31504414
47 + 31504367 = 31504414
281 + 31504133 = 31504414
311 + 31504103 = 31504414
317 + 31504097 = 31504414
401 + 31504013 = 31504414
443 + 31503971 = 31504414
503 + 31503911 = 31504414

Showing the first eight; more decompositions exist.
