Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453038, here are decompositions:

17 + 31453021 = 31453038
61 + 31452977 = 31453038
137 + 31452901 = 31453038
179 + 31452859 = 31453038
269 + 31452769 = 31453038
307 + 31452731 = 31453038
311 + 31452727 = 31453038
317 + 31452721 = 31453038

Showing the first eight; more decompositions exist.
