Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481084, here are decompositions:

7 + 31481077 = 31481084
73 + 31481011 = 31481084
211 + 31480873 = 31481084
223 + 31480861 = 31481084
463 + 31480621 = 31481084
577 + 31480507 = 31481084
643 + 31480441 = 31481084
883 + 31480201 = 31481084

Showing the first eight; more decompositions exist.
