Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480434, here are decompositions:

43 + 31480391 = 31480434
53 + 31480381 = 31480434
61 + 31480373 = 31480434
67 + 31480367 = 31480434
233 + 31480201 = 31480434
317 + 31480117 = 31480434
331 + 31480103 = 31480434
373 + 31480061 = 31480434

Showing the first eight; more decompositions exist.
