Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504622, here are decompositions:

3 + 31504619 = 31504622
31 + 31504591 = 31504622
271 + 31504351 = 31504622
421 + 31504201 = 31504622
433 + 31504189 = 31504622
439 + 31504183 = 31504622
571 + 31504051 = 31504622
661 + 31503961 = 31504622

Showing the first eight; more decompositions exist.
