Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619852, here are decompositions:

3 + 31619849 = 31619852
31 + 31619821 = 31619852
139 + 31619713 = 31619852
241 + 31619611 = 31619852
331 + 31619521 = 31619852
463 + 31619389 = 31619852
541 + 31619311 = 31619852
571 + 31619281 = 31619852

Showing the first eight; more decompositions exist.
