Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553932, here are decompositions:

29 + 31553903 = 31553932
131 + 31553801 = 31553932
149 + 31553783 = 31553932
173 + 31553759 = 31553932
269 + 31553663 = 31553932
479 + 31553453 = 31553932
563 + 31553369 = 31553932
593 + 31553339 = 31553932

Showing the first eight; more decompositions exist.
