Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541662, here are decompositions:

3 + 31541659 = 31541662
11 + 31541651 = 31541662
29 + 31541633 = 31541662
71 + 31541591 = 31541662
179 + 31541483 = 31541662
233 + 31541429 = 31541662
263 + 31541399 = 31541662
419 + 31541243 = 31541662

Showing the first eight; more decompositions exist.
