Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566654, here are decompositions:

23 + 31566631 = 31566654
43 + 31566611 = 31566654
107 + 31566547 = 31566654
113 + 31566541 = 31566654
127 + 31566527 = 31566654
131 + 31566523 = 31566654
137 + 31566517 = 31566654
157 + 31566497 = 31566654

Showing the first eight; more decompositions exist.
