Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446622, here are decompositions:

29 + 31446593 = 31446622
59 + 31446563 = 31446622
89 + 31446533 = 31446622
131 + 31446491 = 31446622
281 + 31446341 = 31446622
293 + 31446329 = 31446622
491 + 31446131 = 31446622
521 + 31446101 = 31446622

Showing the first eight; more decompositions exist.
