Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461844, here are decompositions:

3 + 31461841 = 31461844
53 + 31461791 = 31461844
83 + 31461761 = 31461844
101 + 31461743 = 31461844
107 + 31461737 = 31461844
191 + 31461653 = 31461844
311 + 31461533 = 31461844
431 + 31461413 = 31461844

Showing the first eight; more decompositions exist.
