Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553164, here are decompositions:

3 + 31553161 = 31553164
101 + 31553063 = 31553164
257 + 31552907 = 31553164
281 + 31552883 = 31553164
311 + 31552853 = 31553164
317 + 31552847 = 31553164
347 + 31552817 = 31553164
431 + 31552733 = 31553164

Showing the first eight; more decompositions exist.
