Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560744, here are decompositions:

13 + 31560731 = 31560744
31 + 31560713 = 31560744
41 + 31560703 = 31560744
67 + 31560677 = 31560744
71 + 31560673 = 31560744
97 + 31560647 = 31560744
113 + 31560631 = 31560744
157 + 31560587 = 31560744

Showing the first eight; more decompositions exist.
