Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474462, here are decompositions:

29 + 31474433 = 31474462
59 + 31474403 = 31474462
389 + 31474073 = 31474462
401 + 31474061 = 31474462
419 + 31474043 = 31474462
491 + 31473971 = 31474462
599 + 31473863 = 31474462
653 + 31473809 = 31474462

Showing the first eight; more decompositions exist.
