Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580274, here are decompositions:

7 + 31580267 = 31580274
17 + 31580257 = 31580274
41 + 31580233 = 31580274
43 + 31580231 = 31580274
53 + 31580221 = 31580274
67 + 31580207 = 31580274
97 + 31580177 = 31580274
163 + 31580111 = 31580274

Showing the first eight; more decompositions exist.
