Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506598, here are decompositions:

29 + 31506569 = 31506598
239 + 31506359 = 31506598
449 + 31506149 = 31506598
479 + 31506119 = 31506598
569 + 31506029 = 31506598
659 + 31505939 = 31506598
677 + 31505921 = 31506598
797 + 31505801 = 31506598

Showing the first eight; more decompositions exist.
