Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566662, here are decompositions:

3 + 31566659 = 31566662
31 + 31566631 = 31566662
73 + 31566589 = 31566662
103 + 31566559 = 31566662
139 + 31566523 = 31566662
181 + 31566481 = 31566662
313 + 31566349 = 31566662
373 + 31566289 = 31566662

Showing the first eight; more decompositions exist.
