Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450184, here are decompositions:

43 + 31450141 = 31450184
67 + 31450117 = 31450184
127 + 31450057 = 31450184
151 + 31450033 = 31450184
163 + 31450021 = 31450184
193 + 31449991 = 31450184
313 + 31449871 = 31450184
331 + 31449853 = 31450184

Showing the first eight; more decompositions exist.
