Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446658, here are decompositions:

17 + 31446641 = 31446658
101 + 31446557 = 31446658
167 + 31446491 = 31446658
197 + 31446461 = 31446658
317 + 31446341 = 31446658
401 + 31446257 = 31446658
431 + 31446227 = 31446658
491 + 31446167 = 31446658

Showing the first eight; more decompositions exist.
