Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480066, here are decompositions:

5 + 31480061 = 31480066
17 + 31480049 = 31480066
47 + 31480019 = 31480066
263 + 31479803 = 31480066
347 + 31479719 = 31480066
419 + 31479647 = 31480066
509 + 31479557 = 31480066
599 + 31479467 = 31480066

Showing the first eight; more decompositions exist.
