Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498556, here are decompositions:

7 + 31498549 = 31498556
43 + 31498513 = 31498556
277 + 31498279 = 31498556
283 + 31498273 = 31498556
367 + 31498189 = 31498556
433 + 31498123 = 31498556
487 + 31498069 = 31498556
547 + 31498009 = 31498556

Showing the first eight; more decompositions exist.
