Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496524, here are decompositions:

5 + 31496519 = 31496524
83 + 31496441 = 31496524
107 + 31496417 = 31496524
263 + 31496261 = 31496524
383 + 31496141 = 31496524
401 + 31496123 = 31496524
467 + 31496057 = 31496524
677 + 31495847 = 31496524

Showing the first eight; more decompositions exist.
