Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452398, here are decompositions:

31 + 31452367 = 31452398
97 + 31452301 = 31452398
157 + 31452241 = 31452398
199 + 31452199 = 31452398
277 + 31452121 = 31452398
337 + 31452061 = 31452398
379 + 31452019 = 31452398
541 + 31451857 = 31452398

Showing the first eight; more decompositions exist.
