Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464884, here are decompositions:

97 + 31464787 = 31464884
103 + 31464781 = 31464884
127 + 31464757 = 31464884
307 + 31464577 = 31464884
313 + 31464571 = 31464884
337 + 31464547 = 31464884
421 + 31464463 = 31464884
433 + 31464451 = 31464884

Showing the first eight; more decompositions exist.
