Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454070, here are decompositions:

17 + 31454053 = 31454070
47 + 31454023 = 31454070
73 + 31453997 = 31454070
79 + 31453991 = 31454070
101 + 31453969 = 31454070
113 + 31453957 = 31454070
127 + 31453943 = 31454070
139 + 31453931 = 31454070

Showing the first eight; more decompositions exist.
