Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454698, here are decompositions:

17 + 31454681 = 31454698
29 + 31454669 = 31454698
47 + 31454651 = 31454698
71 + 31454627 = 31454698
257 + 31454441 = 31454698
347 + 31454351 = 31454698
449 + 31454249 = 31454698
479 + 31454219 = 31454698

Showing the first eight; more decompositions exist.
