Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480734, here are decompositions:

41 + 31480693 = 31480734
53 + 31480681 = 31480734
113 + 31480621 = 31480734
227 + 31480507 = 31480734
293 + 31480441 = 31480734
353 + 31480381 = 31480734
367 + 31480367 = 31480734
617 + 31480117 = 31480734

Showing the first eight; more decompositions exist.
