Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446892, here are decompositions:

53 + 31446839 = 31446892
131 + 31446761 = 31446892
149 + 31446743 = 31446892
251 + 31446641 = 31446892
359 + 31446533 = 31446892
401 + 31446491 = 31446892
431 + 31446461 = 31446892
563 + 31446329 = 31446892

Showing the first eight; more decompositions exist.
