Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555496, here are decompositions:

3 + 31555493 = 31555496
67 + 31555429 = 31555496
109 + 31555387 = 31555496
199 + 31555297 = 31555496
229 + 31555267 = 31555496
397 + 31555099 = 31555496
433 + 31555063 = 31555496
547 + 31554949 = 31555496

Showing the first eight; more decompositions exist.
