Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473556, here are decompositions:

197 + 31473359 = 31473556
293 + 31473263 = 31473556
347 + 31473209 = 31473556
353 + 31473203 = 31473556
383 + 31473173 = 31473556
449 + 31473107 = 31473556
479 + 31473077 = 31473556
593 + 31472963 = 31473556

Showing the first eight; more decompositions exist.
