Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454184, here are decompositions:

23 + 31454161 = 31454184
37 + 31454147 = 31454184
61 + 31454123 = 31454184
67 + 31454117 = 31454184
101 + 31454083 = 31454184
103 + 31454081 = 31454184
107 + 31454077 = 31454184
131 + 31454053 = 31454184

Showing the first eight; more decompositions exist.
