Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619424, here are decompositions:

17 + 31619407 = 31619424
37 + 31619387 = 31619424
97 + 31619327 = 31619424
113 + 31619311 = 31619424
157 + 31619267 = 31619424
163 + 31619261 = 31619424
167 + 31619257 = 31619424
211 + 31619213 = 31619424

Showing the first eight; more decompositions exist.
