Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469036, here are decompositions:

3 + 31469033 = 31469036
43 + 31468993 = 31469036
73 + 31468963 = 31469036
337 + 31468699 = 31469036
439 + 31468597 = 31469036
463 + 31468573 = 31469036
877 + 31468159 = 31469036
1009 + 31468027 = 31469036

Showing the first eight; more decompositions exist.
