Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461924, here are decompositions:

5 + 31461919 = 31461924
31 + 31461893 = 31461924
37 + 31461887 = 31461924
73 + 31461851 = 31461924
83 + 31461841 = 31461924
101 + 31461823 = 31461924
107 + 31461817 = 31461924
113 + 31461811 = 31461924

Showing the first eight; more decompositions exist.
