Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619274, here are decompositions:

7 + 31619267 = 31619274
13 + 31619261 = 31619274
17 + 31619257 = 31619274
61 + 31619213 = 31619274
67 + 31619207 = 31619274
83 + 31619191 = 31619274
97 + 31619177 = 31619274
103 + 31619171 = 31619274

Showing the first eight; more decompositions exist.
