Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589506, here are decompositions:

23 + 31589483 = 31589506
83 + 31589423 = 31589506
167 + 31589339 = 31589506
173 + 31589333 = 31589506
419 + 31589087 = 31589506
449 + 31589057 = 31589506
479 + 31589027 = 31589506
563 + 31588943 = 31589506

Showing the first eight; more decompositions exist.
