Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461852, here are decompositions:

11 + 31461841 = 31461852
29 + 31461823 = 31461852
41 + 31461811 = 31461852
61 + 31461791 = 31461852
73 + 31461779 = 31461852
89 + 31461763 = 31461852
109 + 31461743 = 31461852
179 + 31461673 = 31461852

Showing the first eight; more decompositions exist.
