Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619058, here are decompositions:

17 + 31619041 = 31619058
41 + 31619017 = 31619058
59 + 31618999 = 31619058
67 + 31618991 = 31619058
109 + 31618949 = 31619058
157 + 31618901 = 31619058
167 + 31618891 = 31619058
179 + 31618879 = 31619058

Showing the first eight; more decompositions exist.
