Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470300, here are decompositions:

7 + 31470293 = 31470300
41 + 31470259 = 31470300
79 + 31470221 = 31470300
83 + 31470217 = 31470300
101 + 31470199 = 31470300
107 + 31470193 = 31470300
149 + 31470151 = 31470300
157 + 31470143 = 31470300

Showing the first eight; more decompositions exist.
