Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619752, here are decompositions:

11 + 31619741 = 31619752
29 + 31619723 = 31619752
83 + 31619669 = 31619752
149 + 31619603 = 31619752
191 + 31619561 = 31619752
233 + 31619519 = 31619752
251 + 31619501 = 31619752
293 + 31619459 = 31619752

Showing the first eight; more decompositions exist.
