Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496588, here are decompositions:

37 + 31496551 = 31496588
139 + 31496449 = 31496588
199 + 31496389 = 31496588
271 + 31496317 = 31496588
367 + 31496221 = 31496588
379 + 31496209 = 31496588
547 + 31496041 = 31496588
577 + 31496011 = 31496588

Showing the first eight; more decompositions exist.
