Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619364, here are decompositions:

5 + 31619359 = 31619364
37 + 31619327 = 31619364
53 + 31619311 = 31619364
83 + 31619281 = 31619364
97 + 31619267 = 31619364
103 + 31619261 = 31619364
107 + 31619257 = 31619364
151 + 31619213 = 31619364

Showing the first eight; more decompositions exist.
