Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504558, here are decompositions:

11 + 31504547 = 31504558
191 + 31504367 = 31504558
431 + 31504127 = 31504558
461 + 31504097 = 31504558
521 + 31504037 = 31504558
587 + 31503971 = 31504558
641 + 31503917 = 31504558
647 + 31503911 = 31504558

Showing the first eight; more decompositions exist.
