Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446052, here are decompositions:

41 + 31446011 = 31446052
191 + 31445861 = 31446052
263 + 31445789 = 31446052
359 + 31445693 = 31446052
389 + 31445663 = 31446052
401 + 31445651 = 31446052
431 + 31445621 = 31446052
479 + 31445573 = 31446052

Showing the first eight; more decompositions exist.
