Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554064, here are decompositions:

53 + 31554011 = 31554064
71 + 31553993 = 31554064
197 + 31553867 = 31554064
257 + 31553807 = 31554064
263 + 31553801 = 31554064
281 + 31553783 = 31554064
401 + 31553663 = 31554064
677 + 31553387 = 31554064

Showing the first eight; more decompositions exist.
