Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446844, here are decompositions:

5 + 31446839 = 31446844
83 + 31446761 = 31446844
101 + 31446743 = 31446844
251 + 31446593 = 31446844
281 + 31446563 = 31446844
311 + 31446533 = 31446844
353 + 31446491 = 31446844
383 + 31446461 = 31446844

Showing the first eight; more decompositions exist.
