Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444804, here are decompositions:

3 + 31444801 = 31444804
113 + 31444691 = 31444804
173 + 31444631 = 31444804
257 + 31444547 = 31444804
263 + 31444541 = 31444804
401 + 31444403 = 31444804
491 + 31444313 = 31444804
557 + 31444247 = 31444804

Showing the first eight; more decompositions exist.
