Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446802, here are decompositions:

41 + 31446761 = 31446802
53 + 31446749 = 31446802
59 + 31446743 = 31446802
113 + 31446689 = 31446802
239 + 31446563 = 31446802
269 + 31446533 = 31446802
311 + 31446491 = 31446802
461 + 31446341 = 31446802

Showing the first eight; more decompositions exist.
