Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450044, here are decompositions:

11 + 31450033 = 31450044
13 + 31450031 = 31450044
23 + 31450021 = 31450044
53 + 31449991 = 31450044
107 + 31449937 = 31450044
113 + 31449931 = 31450044
173 + 31449871 = 31450044
191 + 31449853 = 31450044

Showing the first eight; more decompositions exist.
