Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503852, here are decompositions:

5 + 31503847 = 31503852
11 + 31503841 = 31503852
41 + 31503811 = 31503852
43 + 31503809 = 31503852
53 + 31503799 = 31503852
73 + 31503779 = 31503852
101 + 31503751 = 31503852
103 + 31503749 = 31503852

Showing the first eight; more decompositions exist.
