Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504516, here are decompositions:

23 + 31504493 = 31504516
149 + 31504367 = 31504516
383 + 31504133 = 31504516
389 + 31504127 = 31504516
419 + 31504097 = 31504516
479 + 31504037 = 31504516
503 + 31504013 = 31504516
587 + 31503929 = 31504516

Showing the first eight; more decompositions exist.
