Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446894, here are decompositions:

23 + 31446871 = 31446894
41 + 31446853 = 31446894
47 + 31446847 = 31446894
137 + 31446757 = 31446894
151 + 31446743 = 31446894
331 + 31446563 = 31446894
337 + 31446557 = 31446894
433 + 31446461 = 31446894

Showing the first eight; more decompositions exist.
