Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473092, here are decompositions:

31 + 31473061 = 31473092
61 + 31473031 = 31473092
109 + 31472983 = 31473092
163 + 31472929 = 31473092
241 + 31472851 = 31473092
613 + 31472479 = 31473092
643 + 31472449 = 31473092
733 + 31472359 = 31473092

Showing the first eight; more decompositions exist.
