Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601052, here are decompositions:

11 + 31601041 = 31601052
29 + 31601023 = 31601052
59 + 31600993 = 31601052
83 + 31600969 = 31601052
191 + 31600861 = 31601052
193 + 31600859 = 31601052
229 + 31600823 = 31601052
251 + 31600801 = 31601052

Showing the first eight; more decompositions exist.
