Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460184, here are decompositions:

11 + 31460173 = 31460184
17 + 31460167 = 31460184
47 + 31460137 = 31460184
131 + 31460053 = 31460184
167 + 31460017 = 31460184
191 + 31459993 = 31460184
293 + 31459891 = 31460184
331 + 31459853 = 31460184

Showing the first eight; more decompositions exist.
