Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468040, here are decompositions:

13 + 31468027 = 31468040
73 + 31467967 = 31468040
103 + 31467937 = 31468040
193 + 31467847 = 31468040
211 + 31467829 = 31468040
229 + 31467811 = 31468040
277 + 31467763 = 31468040
313 + 31467727 = 31468040

Showing the first eight; more decompositions exist.
