Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534470, here are decompositions:

13 + 31534457 = 31534470
29 + 31534441 = 31534470
41 + 31534429 = 31534470
43 + 31534427 = 31534470
47 + 31534423 = 31534470
59 + 31534411 = 31534470
101 + 31534369 = 31534470
127 + 31534343 = 31534470

Showing the first eight; more decompositions exist.
