Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454796, here are decompositions:

13 + 31454783 = 31454796
59 + 31454737 = 31454796
127 + 31454669 = 31454796
283 + 31454513 = 31454796
313 + 31454483 = 31454796
419 + 31454377 = 31454796
547 + 31454249 = 31454796
577 + 31454219 = 31454796

Showing the first eight; more decompositions exist.
