Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446836, here are decompositions:

67 + 31446769 = 31446836
79 + 31446757 = 31446836
97 + 31446739 = 31446836
229 + 31446607 = 31446836
283 + 31446553 = 31446836
397 + 31446439 = 31446836
409 + 31446427 = 31446836
607 + 31446229 = 31446836

Showing the first eight; more decompositions exist.
