Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483618, here are decompositions:

41 + 31483577 = 31483618
71 + 31483547 = 31483618
149 + 31483469 = 31483618
227 + 31483391 = 31483618
311 + 31483307 = 31483618
389 + 31483229 = 31483618
401 + 31483217 = 31483618
449 + 31483169 = 31483618

Showing the first eight; more decompositions exist.
