Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446412, here are decompositions:

71 + 31446341 = 31446412
83 + 31446329 = 31446412
89 + 31446323 = 31446412
281 + 31446131 = 31446412
311 + 31446101 = 31446412
359 + 31446053 = 31446412
401 + 31446011 = 31446412
521 + 31445891 = 31446412

Showing the first eight; more decompositions exist.
