Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468536, here are decompositions:

7 + 31468529 = 31468536
13 + 31468523 = 31468536
19 + 31468517 = 31468536
37 + 31468499 = 31468536
83 + 31468453 = 31468536
89 + 31468447 = 31468536
137 + 31468399 = 31468536
139 + 31468397 = 31468536

Showing the first eight; more decompositions exist.
