Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589098, here are decompositions:

11 + 31589087 = 31589098
29 + 31589069 = 31589098
41 + 31589057 = 31589098
71 + 31589027 = 31589098
251 + 31588847 = 31589098
389 + 31588709 = 31589098
419 + 31588679 = 31589098
467 + 31588631 = 31589098

Showing the first eight; more decompositions exist.
