Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553722, here are decompositions:

3 + 31553719 = 31553722
59 + 31553663 = 31553722
113 + 31553609 = 31553722
269 + 31553453 = 31553722
353 + 31553369 = 31553722
383 + 31553339 = 31553722
401 + 31553321 = 31553722
443 + 31553279 = 31553722

Showing the first eight; more decompositions exist.
