Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504654, here are decompositions:

3 + 31504651 = 31504654
47 + 31504607 = 31504654
107 + 31504547 = 31504654
173 + 31504481 = 31504654
281 + 31504373 = 31504654
521 + 31504133 = 31504654
557 + 31504097 = 31504654
617 + 31504037 = 31504654

Showing the first eight; more decompositions exist.
