Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589498, here are decompositions:

37 + 31589461 = 31589498
97 + 31589401 = 31589498
139 + 31589359 = 31589498
181 + 31589317 = 31589498
211 + 31589287 = 31589498
331 + 31589167 = 31589498
379 + 31589119 = 31589498
487 + 31589011 = 31589498

Showing the first eight; more decompositions exist.
