Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554852, here are decompositions:

11 + 31554841 = 31554852
23 + 31554829 = 31554852
29 + 31554823 = 31554852
41 + 31554811 = 31554852
61 + 31554791 = 31554852
103 + 31554749 = 31554852
113 + 31554739 = 31554852
181 + 31554671 = 31554852

Showing the first eight; more decompositions exist.
