Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480554, here are decompositions:

47 + 31480507 = 31480554
113 + 31480441 = 31480554
163 + 31480391 = 31480554
173 + 31480381 = 31480554
181 + 31480373 = 31480554
353 + 31480201 = 31480554
463 + 31480091 = 31480554
593 + 31479961 = 31480554

Showing the first eight; more decompositions exist.
