Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480168, here are decompositions:

89 + 31480079 = 31480168
107 + 31480061 = 31480168
149 + 31480019 = 31480168
311 + 31479857 = 31480168
347 + 31479821 = 31480168
431 + 31479737 = 31480168
449 + 31479719 = 31480168
521 + 31479647 = 31480168

Showing the first eight; more decompositions exist.
