Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477492, here are decompositions:

113 + 31477379 = 31477492
191 + 31477301 = 31477492
311 + 31477181 = 31477492
881 + 31476611 = 31477492
941 + 31476551 = 31477492
983 + 31476509 = 31477492
1031 + 31476461 = 31477492
1109 + 31476383 = 31477492

Showing the first eight; more decompositions exist.
