Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465308, here are decompositions:

19 + 31465289 = 31465308
131 + 31465177 = 31465308
179 + 31465129 = 31465308
197 + 31465111 = 31465308
239 + 31465069 = 31465308
269 + 31465039 = 31465308
317 + 31464991 = 31465308
367 + 31464941 = 31465308

Showing the first eight; more decompositions exist.
