Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473090, here are decompositions:

7 + 31473083 = 31473090
13 + 31473077 = 31473090
23 + 31473067 = 31473090
29 + 31473061 = 31473090
53 + 31473037 = 31473090
59 + 31473031 = 31473090
107 + 31472983 = 31473090
127 + 31472963 = 31473090

Showing the first eight; more decompositions exist.
