Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464944, here are decompositions:

3 + 31464941 = 31464944
61 + 31464883 = 31464944
157 + 31464787 = 31464944
163 + 31464781 = 31464944
367 + 31464577 = 31464944
373 + 31464571 = 31464944
397 + 31464547 = 31464944
463 + 31464481 = 31464944

Showing the first eight; more decompositions exist.
