Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464626, here are decompositions:

7 + 31464619 = 31464626
79 + 31464547 = 31464626
163 + 31464463 = 31464626
199 + 31464427 = 31464626
229 + 31464397 = 31464626
433 + 31464193 = 31464626
439 + 31464187 = 31464626
547 + 31464079 = 31464626

Showing the first eight; more decompositions exist.
