Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452338, here are decompositions:

37 + 31452301 = 31452338
97 + 31452241 = 31452338
139 + 31452199 = 31452338
157 + 31452181 = 31452338
241 + 31452097 = 31452338
277 + 31452061 = 31452338
331 + 31452007 = 31452338
409 + 31451929 = 31452338

Showing the first eight; more decompositions exist.
