Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465946, here are decompositions:

67 + 31465879 = 31465946
97 + 31465849 = 31465946
157 + 31465789 = 31465946
199 + 31465747 = 31465946
283 + 31465663 = 31465946
367 + 31465579 = 31465946
487 + 31465459 = 31465946
769 + 31465177 = 31465946

Showing the first eight; more decompositions exist.
