Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606262, here are decompositions:

211 + 31606051 = 31606262
349 + 31605913 = 31606262
439 + 31605823 = 31606262
643 + 31605619 = 31606262
691 + 31605571 = 31606262
823 + 31605439 = 31606262
991 + 31605271 = 31606262
1033 + 31605229 = 31606262

Showing the first eight; more decompositions exist.
