Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619184, here are decompositions:

5 + 31619179 = 31619184
7 + 31619177 = 31619184
13 + 31619171 = 31619184
41 + 31619143 = 31619184
61 + 31619123 = 31619184
67 + 31619117 = 31619184
167 + 31619017 = 31619184
193 + 31618991 = 31619184

Showing the first eight; more decompositions exist.
