Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446558, here are decompositions:

5 + 31446553 = 31446558
67 + 31446491 = 31446558
97 + 31446461 = 31446558
131 + 31446427 = 31446558
191 + 31446367 = 31446558
197 + 31446361 = 31446558
229 + 31446329 = 31446558
307 + 31446251 = 31446558

Showing the first eight; more decompositions exist.
