Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544670, here are decompositions:

13 + 31544657 = 31544670
83 + 31544587 = 31544670
97 + 31544573 = 31544670
109 + 31544561 = 31544670
127 + 31544543 = 31544670
137 + 31544533 = 31544670
139 + 31544531 = 31544670
277 + 31544393 = 31544670

Showing the first eight; more decompositions exist.
