Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504662, here are decompositions:

11 + 31504651 = 31504662
43 + 31504619 = 31504662
71 + 31504591 = 31504662
89 + 31504573 = 31504662
181 + 31504481 = 31504662
223 + 31504439 = 31504662
311 + 31504351 = 31504662
359 + 31504303 = 31504662

Showing the first eight; more decompositions exist.
