Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496488, here are decompositions:

47 + 31496441 = 31496488
59 + 31496429 = 31496488
71 + 31496417 = 31496488
167 + 31496321 = 31496488
227 + 31496261 = 31496488
269 + 31496219 = 31496488
347 + 31496141 = 31496488
389 + 31496099 = 31496488

Showing the first eight; more decompositions exist.
