Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473598, here are decompositions:

5 + 31473593 = 31473598
17 + 31473581 = 31473598
239 + 31473359 = 31473598
347 + 31473251 = 31473598
389 + 31473209 = 31473598
491 + 31473107 = 31473598
521 + 31473077 = 31473598
557 + 31473041 = 31473598

Showing the first eight; more decompositions exist.
