Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542022, here are decompositions:

11 + 31542011 = 31542022
41 + 31541981 = 31542022
89 + 31541933 = 31542022
131 + 31541891 = 31542022
389 + 31541633 = 31542022
431 + 31541591 = 31542022
593 + 31541429 = 31542022
881 + 31541141 = 31542022

Showing the first eight; more decompositions exist.
