Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446718, here are decompositions:

29 + 31446689 = 31446718
227 + 31446491 = 31446718
257 + 31446461 = 31446718
389 + 31446329 = 31446718
461 + 31446257 = 31446718
467 + 31446251 = 31446718
491 + 31446227 = 31446718
587 + 31446131 = 31446718

Showing the first eight; more decompositions exist.
