Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446382, here are decompositions:

41 + 31446341 = 31446382
53 + 31446329 = 31446382
59 + 31446323 = 31446382
131 + 31446251 = 31446382
251 + 31446131 = 31446382
281 + 31446101 = 31446382
491 + 31445891 = 31446382
521 + 31445861 = 31446382

Showing the first eight; more decompositions exist.
