Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480764, here are decompositions:

31 + 31480733 = 31480764
71 + 31480693 = 31480764
83 + 31480681 = 31480764
257 + 31480507 = 31480764
331 + 31480433 = 31480764
373 + 31480391 = 31480764
383 + 31480381 = 31480764
397 + 31480367 = 31480764

Showing the first eight; more decompositions exist.
