Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446244, here are decompositions:

3 + 31446241 = 31446244
17 + 31446227 = 31446244
113 + 31446131 = 31446244
191 + 31446053 = 31446244
233 + 31446011 = 31446244
353 + 31445891 = 31446244
383 + 31445861 = 31446244
521 + 31445723 = 31446244

Showing the first eight; more decompositions exist.
