Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467854, here are decompositions:

7 + 31467847 = 31467854
43 + 31467811 = 31467854
127 + 31467727 = 31467854
163 + 31467691 = 31467854
283 + 31467571 = 31467854
373 + 31467481 = 31467854
421 + 31467433 = 31467854
487 + 31467367 = 31467854

Showing the first eight; more decompositions exist.
