Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480030, here are decompositions:

11 + 31480019 = 31480030
83 + 31479947 = 31480030
149 + 31479881 = 31480030
173 + 31479857 = 31480030
227 + 31479803 = 31480030
293 + 31479737 = 31480030
311 + 31479719 = 31480030
359 + 31479671 = 31480030

Showing the first eight; more decompositions exist.
