Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619324, here are decompositions:

13 + 31619311 = 31619324
43 + 31619281 = 31619324
67 + 31619257 = 31619324
181 + 31619143 = 31619324
283 + 31619041 = 31619324
307 + 31619017 = 31619324
433 + 31618891 = 31619324
547 + 31618777 = 31619324

Showing the first eight; more decompositions exist.
