Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617558, here are decompositions:

29 + 31617529 = 31617558
61 + 31617497 = 31617558
97 + 31617461 = 31617558
101 + 31617457 = 31617558
109 + 31617449 = 31617558
127 + 31617431 = 31617558
149 + 31617409 = 31617558
151 + 31617407 = 31617558

Showing the first eight; more decompositions exist.
