Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452908, here are decompositions:

7 + 31452901 = 31452908
79 + 31452829 = 31452908
139 + 31452769 = 31452908
181 + 31452727 = 31452908
241 + 31452667 = 31452908
337 + 31452571 = 31452908
379 + 31452529 = 31452908
457 + 31452451 = 31452908

Showing the first eight; more decompositions exist.
