Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453330, here are decompositions:

47 + 31453283 = 31453330
89 + 31453241 = 31453330
137 + 31453193 = 31453330
149 + 31453181 = 31453330
173 + 31453157 = 31453330
197 + 31453133 = 31453330
353 + 31452977 = 31453330
479 + 31452851 = 31453330

Showing the first eight; more decompositions exist.
