Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480462, here are decompositions:

29 + 31480433 = 31480462
71 + 31480391 = 31480462
89 + 31480373 = 31480462
113 + 31480349 = 31480462
173 + 31480289 = 31480462
359 + 31480103 = 31480462
383 + 31480079 = 31480462
401 + 31480061 = 31480462

Showing the first eight; more decompositions exist.
