Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589314, here are decompositions:

11 + 31589303 = 31589314
17 + 31589297 = 31589314
23 + 31589291 = 31589314
131 + 31589183 = 31589314
227 + 31589087 = 31589314
257 + 31589057 = 31589314
467 + 31588847 = 31589314
641 + 31588673 = 31589314

Showing the first eight; more decompositions exist.
