Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483270, here are decompositions:

41 + 31483229 = 31483270
53 + 31483217 = 31483270
101 + 31483169 = 31483270
107 + 31483163 = 31483270
173 + 31483097 = 31483270
293 + 31482977 = 31483270
431 + 31482839 = 31483270
449 + 31482821 = 31483270

Showing the first eight; more decompositions exist.
