Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553944, here are decompositions:

41 + 31553903 = 31553944
137 + 31553807 = 31553944
167 + 31553777 = 31553944
281 + 31553663 = 31553944
491 + 31553453 = 31553944
557 + 31553387 = 31553944
593 + 31553351 = 31553944
683 + 31553261 = 31553944

Showing the first eight; more decompositions exist.
