Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553976, here are decompositions:

73 + 31553903 = 31553976
109 + 31553867 = 31553976
173 + 31553803 = 31553976
193 + 31553783 = 31553976
199 + 31553777 = 31553976
257 + 31553719 = 31553976
269 + 31553707 = 31553976
313 + 31553663 = 31553976

Showing the first eight; more decompositions exist.
