Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619134, here are decompositions:

5 + 31619129 = 31619134
11 + 31619123 = 31619134
17 + 31619117 = 31619134
191 + 31618943 = 31619134
233 + 31618901 = 31619134
251 + 31618883 = 31619134
263 + 31618871 = 31619134
311 + 31618823 = 31619134

Showing the first eight; more decompositions exist.
