Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619322, here are decompositions:

11 + 31619311 = 31619322
41 + 31619281 = 31619322
61 + 31619261 = 31619322
109 + 31619213 = 31619322
113 + 31619209 = 31619322
131 + 31619191 = 31619322
139 + 31619183 = 31619322
151 + 31619171 = 31619322

Showing the first eight; more decompositions exist.
