Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496170, here are decompositions:

29 + 31496141 = 31496170
47 + 31496123 = 31496170
71 + 31496099 = 31496170
113 + 31496057 = 31496170
191 + 31495979 = 31496170
311 + 31495859 = 31496170
479 + 31495691 = 31496170
509 + 31495661 = 31496170

Showing the first eight; more decompositions exist.
