Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446610, here are decompositions:

3 + 31446607 = 31446610
17 + 31446593 = 31446610
47 + 31446563 = 31446610
53 + 31446557 = 31446610
149 + 31446461 = 31446610
269 + 31446341 = 31446610
281 + 31446329 = 31446610
353 + 31446257 = 31446610

Showing the first eight; more decompositions exist.
