Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554562, here are decompositions:

23 + 31554539 = 31554562
89 + 31554473 = 31554562
113 + 31554449 = 31554562
383 + 31554179 = 31554562
401 + 31554161 = 31554562
419 + 31554143 = 31554562
569 + 31553993 = 31554562
659 + 31553903 = 31554562

Showing the first eight; more decompositions exist.
