Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496554, here are decompositions:

3 + 31496551 = 31496554
17 + 31496537 = 31496554
113 + 31496441 = 31496554
137 + 31496417 = 31496554
233 + 31496321 = 31496554
293 + 31496261 = 31496554
431 + 31496123 = 31496554
797 + 31495757 = 31496554

Showing the first eight; more decompositions exist.
