Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480150, here are decompositions:

47 + 31480103 = 31480150
59 + 31480091 = 31480150
71 + 31480079 = 31480150
89 + 31480061 = 31480150
101 + 31480049 = 31480150
131 + 31480019 = 31480150
269 + 31479881 = 31480150
293 + 31479857 = 31480150

Showing the first eight; more decompositions exist.
