Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453044, here are decompositions:

5 + 31453039 = 31453044
23 + 31453021 = 31453044
67 + 31452977 = 31453044
71 + 31452973 = 31453044
101 + 31452943 = 31453044
193 + 31452851 = 31453044
241 + 31452803 = 31453044
251 + 31452793 = 31453044

Showing the first eight; more decompositions exist.
