Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553968, here are decompositions:

101 + 31553867 = 31553968
167 + 31553801 = 31553968
191 + 31553777 = 31553968
239 + 31553729 = 31553968
359 + 31553609 = 31553968
449 + 31553519 = 31553968
599 + 31553369 = 31553968
617 + 31553351 = 31553968

Showing the first eight; more decompositions exist.
