Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480022, here are decompositions:

3 + 31480019 = 31480022
61 + 31479961 = 31480022
73 + 31479949 = 31480022
193 + 31479829 = 31480022
229 + 31479793 = 31480022
283 + 31479739 = 31480022
373 + 31479649 = 31480022
433 + 31479589 = 31480022

Showing the first eight; more decompositions exist.
