Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589708, here are decompositions:

97 + 31589611 = 31589708
307 + 31589401 = 31589708
331 + 31589377 = 31589708
349 + 31589359 = 31589708
379 + 31589329 = 31589708
421 + 31589287 = 31589708
457 + 31589251 = 31589708
541 + 31589167 = 31589708

Showing the first eight; more decompositions exist.
