Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454082, here are decompositions:

5 + 31454077 = 31454082
29 + 31454053 = 31454082
59 + 31454023 = 31454082
89 + 31453993 = 31454082
113 + 31453969 = 31454082
139 + 31453943 = 31454082
151 + 31453931 = 31454082
173 + 31453909 = 31454082

Showing the first eight; more decompositions exist.
