Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446262, here are decompositions:

5 + 31446257 = 31446262
11 + 31446251 = 31446262
131 + 31446131 = 31446262
251 + 31446011 = 31446262
401 + 31445861 = 31446262
569 + 31445693 = 31446262
599 + 31445663 = 31446262
641 + 31445621 = 31446262

Showing the first eight; more decompositions exist.
