Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483420, here are decompositions:

29 + 31483391 = 31483420
107 + 31483313 = 31483420
113 + 31483307 = 31483420
191 + 31483229 = 31483420
251 + 31483169 = 31483420
257 + 31483163 = 31483420
359 + 31483061 = 31483420
443 + 31482977 = 31483420

Showing the first eight; more decompositions exist.
