Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480862, here are decompositions:

13 + 31480849 = 31480862
181 + 31480681 = 31480862
223 + 31480639 = 31480862
241 + 31480621 = 31480862
421 + 31480441 = 31480862
661 + 31480201 = 31480862
733 + 31480129 = 31480862
1033 + 31479829 = 31480862

Showing the first eight; more decompositions exist.
