Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537152, here are decompositions:

31 + 33537121 = 33537152
211 + 33536941 = 33537152
619 + 33536533 = 33537152
991 + 33536161 = 33537152
1033 + 33536119 = 33537152
1123 + 33536029 = 33537152
1249 + 33535903 = 33537152
1399 + 33535753 = 33537152

Showing the first eight; more decompositions exist.
