Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527946, here are decompositions:

5 + 31527941 = 31527946
59 + 31527887 = 31527946
257 + 31527689 = 31527946
269 + 31527677 = 31527946
449 + 31527497 = 31527946
557 + 31527389 = 31527946
773 + 31527173 = 31527946
797 + 31527149 = 31527946

Showing the first eight; more decompositions exist.
