Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448044, here are decompositions:

11 + 31448033 = 31448044
83 + 31447961 = 31448044
113 + 31447931 = 31448044
191 + 31447853 = 31448044
233 + 31447811 = 31448044
293 + 31447751 = 31448044
401 + 31447643 = 31448044
461 + 31447583 = 31448044

Showing the first eight; more decompositions exist.
