Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541456, here are decompositions:

7 + 31541449 = 31541456
19 + 31541437 = 31541456
97 + 31541359 = 31541456
109 + 31541347 = 31541456
223 + 31541233 = 31541456
277 + 31541179 = 31541456
283 + 31541173 = 31541456
409 + 31541047 = 31541456

Showing the first eight; more decompositions exist.
