Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454174, here are decompositions:

13 + 31454161 = 31454174
97 + 31454077 = 31454174
151 + 31454023 = 31454174
181 + 31453993 = 31454174
277 + 31453897 = 31454174
307 + 31453867 = 31454174
463 + 31453711 = 31454174
523 + 31453651 = 31454174

Showing the first eight; more decompositions exist.
