Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504624, here are decompositions:

5 + 31504619 = 31504624
17 + 31504607 = 31504624
131 + 31504493 = 31504624
251 + 31504373 = 31504624
257 + 31504367 = 31504624
491 + 31504133 = 31504624
521 + 31504103 = 31504624
587 + 31504037 = 31504624

Showing the first eight; more decompositions exist.
