Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446506, here are decompositions:

67 + 31446439 = 31446506
79 + 31446427 = 31446506
139 + 31446367 = 31446506
277 + 31446229 = 31446506
283 + 31446223 = 31446506
373 + 31446133 = 31446506
409 + 31446097 = 31446506
439 + 31446067 = 31446506

Showing the first eight; more decompositions exist.
