Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619652, here are decompositions:

5 + 31619647 = 31619652
41 + 31619611 = 31619652
109 + 31619543 = 31619652
131 + 31619521 = 31619652
151 + 31619501 = 31619652
193 + 31619459 = 31619652
263 + 31619389 = 31619652
293 + 31619359 = 31619652

Showing the first eight; more decompositions exist.
