Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480476, here are decompositions:

43 + 31480433 = 31480476
103 + 31480373 = 31480476
107 + 31480369 = 31480476
109 + 31480367 = 31480476
127 + 31480349 = 31480476
347 + 31480129 = 31480476
359 + 31480117 = 31480476
373 + 31480103 = 31480476

Showing the first eight; more decompositions exist.
