Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504746, here are decompositions:

43 + 31504703 = 31504746
79 + 31504667 = 31504746
127 + 31504619 = 31504746
139 + 31504607 = 31504746
173 + 31504573 = 31504746
179 + 31504567 = 31504746
199 + 31504547 = 31504746
293 + 31504453 = 31504746

Showing the first eight; more decompositions exist.
