Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496288, here are decompositions:

67 + 31496221 = 31496288
79 + 31496209 = 31496288
127 + 31496161 = 31496288
277 + 31496011 = 31496288
367 + 31495921 = 31496288
409 + 31495879 = 31496288
487 + 31495801 = 31496288
547 + 31495741 = 31496288

Showing the first eight; more decompositions exist.
