Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496564, here are decompositions:

13 + 31496551 = 31496564
193 + 31496371 = 31496564
271 + 31496293 = 31496564
523 + 31496041 = 31496564
643 + 31495921 = 31496564
811 + 31495753 = 31496564
823 + 31495741 = 31496564
907 + 31495657 = 31496564

Showing the first eight; more decompositions exist.
