Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547302, here are decompositions:

5 + 31547297 = 31547302
41 + 31547261 = 31547302
71 + 31547231 = 31547302
173 + 31547129 = 31547302
239 + 31547063 = 31547302
263 + 31547039 = 31547302
389 + 31546913 = 31547302
503 + 31546799 = 31547302

Showing the first eight; more decompositions exist.
