Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496644, here are decompositions:

71 + 31496573 = 31496644
107 + 31496537 = 31496644
227 + 31496417 = 31496644
383 + 31496261 = 31496644
503 + 31496141 = 31496644
521 + 31496123 = 31496644
587 + 31496057 = 31496644
617 + 31496027 = 31496644

Showing the first eight; more decompositions exist.
