Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446534, here are decompositions:

43 + 31446491 = 31446534
73 + 31446461 = 31446534
107 + 31446427 = 31446534
167 + 31446367 = 31446534
173 + 31446361 = 31446534
193 + 31446341 = 31446534
211 + 31446323 = 31446534
277 + 31446257 = 31446534

Showing the first eight; more decompositions exist.
