Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554724, here are decompositions:

53 + 31554671 = 31554724
83 + 31554641 = 31554724
107 + 31554617 = 31554724
197 + 31554527 = 31554724
251 + 31554473 = 31554724
563 + 31554161 = 31554724
647 + 31554077 = 31554724
821 + 31553903 = 31554724

Showing the first eight; more decompositions exist.
