Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547268, here are decompositions:

7 + 31547261 = 31547268
37 + 31547231 = 31547268
59 + 31547209 = 31547268
107 + 31547161 = 31547268
139 + 31547129 = 31547268
167 + 31547101 = 31547268
191 + 31547077 = 31547268
229 + 31547039 = 31547268

Showing the first eight; more decompositions exist.
