Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473588, here are decompositions:

5 + 31473583 = 31473588
7 + 31473581 = 31473588
59 + 31473529 = 31473588
101 + 31473487 = 31473588
109 + 31473479 = 31473588
131 + 31473457 = 31473588
151 + 31473437 = 31473588
191 + 31473397 = 31473588

Showing the first eight; more decompositions exist.
