Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566434, here are decompositions:

7 + 31566427 = 31566434
37 + 31566397 = 31566434
283 + 31566151 = 31566434
373 + 31566061 = 31566434
421 + 31566013 = 31566434
433 + 31566001 = 31566434
463 + 31565971 = 31566434
547 + 31565887 = 31566434

Showing the first eight; more decompositions exist.
