Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504534, here are decompositions:

41 + 31504493 = 31504534
53 + 31504481 = 31504534
167 + 31504367 = 31504534
401 + 31504133 = 31504534
431 + 31504103 = 31504534
521 + 31504013 = 31504534
557 + 31503977 = 31504534
563 + 31503971 = 31504534

Showing the first eight; more decompositions exist.
