Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505062, here are decompositions:

23 + 31505039 = 31505062
59 + 31505003 = 31505062
179 + 31504883 = 31505062
263 + 31504799 = 31505062
359 + 31504703 = 31505062
401 + 31504661 = 31505062
443 + 31504619 = 31505062
569 + 31504493 = 31505062

Showing the first eight; more decompositions exist.
