Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464894, here are decompositions:

11 + 31464883 = 31464894
67 + 31464827 = 31464894
73 + 31464821 = 31464894
107 + 31464787 = 31464894
113 + 31464781 = 31464894
137 + 31464757 = 31464894
163 + 31464731 = 31464894
193 + 31464701 = 31464894

Showing the first eight; more decompositions exist.
