Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444984, here are decompositions:

47 + 31444937 = 31444984
83 + 31444901 = 31444984
107 + 31444877 = 31444984
113 + 31444871 = 31444984
257 + 31444727 = 31444984
293 + 31444691 = 31444984
353 + 31444631 = 31444984
443 + 31444541 = 31444984

Showing the first eight; more decompositions exist.
