Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534506, here are decompositions:

5 + 31534501 = 31534506
13 + 31534493 = 31534506
19 + 31534487 = 31534506
23 + 31534483 = 31534506
79 + 31534427 = 31534506
83 + 31534423 = 31534506
137 + 31534369 = 31534506
163 + 31534343 = 31534506

Showing the first eight; more decompositions exist.
