Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446106, here are decompositions:

5 + 31446101 = 31446106
53 + 31446053 = 31446106
149 + 31445957 = 31446106
257 + 31445849 = 31446106
317 + 31445789 = 31446106
383 + 31445723 = 31446106
443 + 31445663 = 31446106
563 + 31445543 = 31446106

Showing the first eight; more decompositions exist.
