Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496126, here are decompositions:

3 + 31496123 = 31496126
7 + 31496119 = 31496126
43 + 31496083 = 31496126
229 + 31495897 = 31496126
307 + 31495819 = 31496126
373 + 31495753 = 31496126
397 + 31495729 = 31496126
433 + 31495693 = 31496126

Showing the first eight; more decompositions exist.
