Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468154, here are decompositions:

7 + 31468147 = 31468154
127 + 31468027 = 31468154
307 + 31467847 = 31468154
433 + 31467721 = 31468154
463 + 31467691 = 31468154
673 + 31467481 = 31468154
787 + 31467367 = 31468154
853 + 31467301 = 31468154

Showing the first eight; more decompositions exist.
