Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504894, here are decompositions:

11 + 31504883 = 31504894
191 + 31504703 = 31504894
227 + 31504667 = 31504894
233 + 31504661 = 31504894
347 + 31504547 = 31504894
401 + 31504493 = 31504894
521 + 31504373 = 31504894
761 + 31504133 = 31504894

Showing the first eight; more decompositions exist.
