Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461824, here are decompositions:

7 + 31461817 = 31461824
13 + 31461811 = 31461824
61 + 31461763 = 31461824
127 + 31461697 = 31461824
151 + 31461673 = 31461824
271 + 31461553 = 31461824
307 + 31461517 = 31461824
337 + 31461487 = 31461824

Showing the first eight; more decompositions exist.
