Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553854, here are decompositions:

47 + 31553807 = 31553854
53 + 31553801 = 31553854
71 + 31553783 = 31553854
191 + 31553663 = 31553854
401 + 31553453 = 31553854
467 + 31553387 = 31553854
503 + 31553351 = 31553854
593 + 31553261 = 31553854

Showing the first eight; more decompositions exist.
