Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473416, here are decompositions:

3 + 31473413 = 31473416
19 + 31473397 = 31473416
103 + 31473313 = 31473416
199 + 31473217 = 31473416
229 + 31473187 = 31473416
307 + 31473109 = 31473416
349 + 31473067 = 31473416
379 + 31473037 = 31473416

Showing the first eight; more decompositions exist.
