Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480296, here are decompositions:

7 + 31480289 = 31480296
37 + 31480259 = 31480296
167 + 31480129 = 31480296
179 + 31480117 = 31480296
193 + 31480103 = 31480296
277 + 31480019 = 31480296
347 + 31479949 = 31480296
349 + 31479947 = 31480296

Showing the first eight; more decompositions exist.
