Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589188, here are decompositions:

5 + 31589183 = 31589188
89 + 31589099 = 31589188
101 + 31589087 = 31589188
131 + 31589057 = 31589188
479 + 31588709 = 31589188
509 + 31588679 = 31589188
557 + 31588631 = 31589188
821 + 31588367 = 31589188

Showing the first eight; more decompositions exist.
