Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461862, here are decompositions:

11 + 31461851 = 31461862
71 + 31461791 = 31461862
83 + 31461779 = 31461862
101 + 31461761 = 31461862
293 + 31461569 = 31461862
449 + 31461413 = 31461862
521 + 31461341 = 31461862
569 + 31461293 = 31461862

Showing the first eight; more decompositions exist.
