Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468562, here are decompositions:

3 + 31468559 = 31468562
19 + 31468543 = 31468562
109 + 31468453 = 31468562
163 + 31468399 = 31468562
193 + 31468369 = 31468562
331 + 31468231 = 31468562
613 + 31467949 = 31468562
709 + 31467853 = 31468562

Showing the first eight; more decompositions exist.
