Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446774, here are decompositions:

5 + 31446769 = 31446774
13 + 31446761 = 31446774
17 + 31446757 = 31446774
31 + 31446743 = 31446774
167 + 31446607 = 31446774
181 + 31446593 = 31446774
211 + 31446563 = 31446774
241 + 31446533 = 31446774

Showing the first eight; more decompositions exist.
