Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454330, here are decompositions:

67 + 31454263 = 31454330
109 + 31454221 = 31454330
139 + 31454191 = 31454330
181 + 31454149 = 31454330
277 + 31454053 = 31454330
307 + 31454023 = 31454330
337 + 31453993 = 31454330
373 + 31453957 = 31454330

Showing the first eight; more decompositions exist.
