Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452118, here are decompositions:

29 + 31452089 = 31452118
149 + 31451969 = 31452118
281 + 31451837 = 31452118
311 + 31451807 = 31452118
317 + 31451801 = 31452118
389 + 31451729 = 31452118
419 + 31451699 = 31452118
461 + 31451657 = 31452118

Showing the first eight; more decompositions exist.
