Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541566, here are decompositions:

3 + 31541563 = 31541566
59 + 31541507 = 31541566
83 + 31541483 = 31541566
137 + 31541429 = 31541566
149 + 31541417 = 31541566
167 + 31541399 = 31541566
269 + 31541297 = 31541566
449 + 31541117 = 31541566

Showing the first eight; more decompositions exist.
