Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481796, here are decompositions:

29 + 31481767 = 31481796
43 + 31481753 = 31481796
53 + 31481743 = 31481796
79 + 31481717 = 31481796
83 + 31481713 = 31481796
113 + 31481683 = 31481796
173 + 31481623 = 31481796
317 + 31481479 = 31481796

Showing the first eight; more decompositions exist.
