Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446292, here are decompositions:

41 + 31446251 = 31446292
191 + 31446101 = 31446292
239 + 31446053 = 31446292
281 + 31446011 = 31446292
401 + 31445891 = 31446292
431 + 31445861 = 31446292
443 + 31445849 = 31446292
503 + 31445789 = 31446292

Showing the first eight; more decompositions exist.
