Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554352, here are decompositions:

173 + 31554179 = 31554352
191 + 31554161 = 31554352
359 + 31553993 = 31554352
449 + 31553903 = 31554352
569 + 31553783 = 31554352
593 + 31553759 = 31554352
743 + 31553609 = 31554352
983 + 31553369 = 31554352

Showing the first eight; more decompositions exist.
