Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547524, here are decompositions:

5 + 31547519 = 31547524
17 + 31547507 = 31547524
53 + 31547471 = 31547524
83 + 31547441 = 31547524
167 + 31547357 = 31547524
227 + 31547297 = 31547524
257 + 31547267 = 31547524
263 + 31547261 = 31547524

Showing the first eight; more decompositions exist.
