Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527566, here are decompositions:

43 + 31527523 = 31527566
67 + 31527499 = 31527566
223 + 31527343 = 31527566
313 + 31527253 = 31527566
373 + 31527193 = 31527566
409 + 31527157 = 31527566
457 + 31527109 = 31527566
613 + 31526953 = 31527566

Showing the first eight; more decompositions exist.
