Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467558, here are decompositions:

7 + 31467551 = 31467558
19 + 31467539 = 31467558
61 + 31467497 = 31467558
127 + 31467431 = 31467558
139 + 31467419 = 31467558
191 + 31467367 = 31467558
211 + 31467347 = 31467558
229 + 31467329 = 31467558

Showing the first eight; more decompositions exist.
