Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480794, here are decompositions:

31 + 31480763 = 31480794
61 + 31480733 = 31480794
101 + 31480693 = 31480794
113 + 31480681 = 31480794
173 + 31480621 = 31480794
353 + 31480441 = 31480794
421 + 31480373 = 31480794
593 + 31480201 = 31480794

Showing the first eight; more decompositions exist.
