Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480266, here are decompositions:

7 + 31480259 = 31480266
137 + 31480129 = 31480266
149 + 31480117 = 31480266
163 + 31480103 = 31480266
317 + 31479949 = 31480266
409 + 31479857 = 31480266
449 + 31479817 = 31480266
463 + 31479803 = 31480266

Showing the first eight; more decompositions exist.
