Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619034, here are decompositions:

17 + 31619017 = 31619034
43 + 31618991 = 31619034
53 + 31618981 = 31619034
137 + 31618897 = 31619034
151 + 31618883 = 31619034
163 + 31618871 = 31619034
211 + 31618823 = 31619034
257 + 31618777 = 31619034

Showing the first eight; more decompositions exist.
