Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446592, here are decompositions:

29 + 31446563 = 31446592
59 + 31446533 = 31446592
101 + 31446491 = 31446592
131 + 31446461 = 31446592
251 + 31446341 = 31446592
263 + 31446329 = 31446592
269 + 31446323 = 31446592
461 + 31446131 = 31446592

Showing the first eight; more decompositions exist.
