Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589476, here are decompositions:

3 + 31589473 = 31589476
53 + 31589423 = 31589476
137 + 31589339 = 31589476
173 + 31589303 = 31589476
179 + 31589297 = 31589476
293 + 31589183 = 31589476
389 + 31589087 = 31589476
419 + 31589057 = 31589476

Showing the first eight; more decompositions exist.
