Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589770, here are decompositions:

11 + 31589759 = 31589770
59 + 31589711 = 31589770
137 + 31589633 = 31589770
257 + 31589513 = 31589770
347 + 31589423 = 31589770
431 + 31589339 = 31589770
449 + 31589321 = 31589770
467 + 31589303 = 31589770

Showing the first eight; more decompositions exist.
