Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473084, here are decompositions:

7 + 31473077 = 31473084
17 + 31473067 = 31473084
23 + 31473061 = 31473084
43 + 31473041 = 31473084
47 + 31473037 = 31473084
53 + 31473031 = 31473084
101 + 31472983 = 31473084
157 + 31472927 = 31473084

Showing the first eight; more decompositions exist.
