Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464772, here are decompositions:

41 + 31464731 = 31464772
71 + 31464701 = 31464772
191 + 31464581 = 31464772
263 + 31464509 = 31464772
431 + 31464341 = 31464772
491 + 31464281 = 31464772
503 + 31464269 = 31464772
809 + 31463963 = 31464772

Showing the first eight; more decompositions exist.
