Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542552, here are decompositions:

5 + 31542547 = 31542552
29 + 31542523 = 31542552
43 + 31542509 = 31542552
73 + 31542479 = 31542552
113 + 31542439 = 31542552
179 + 31542373 = 31542552
193 + 31542359 = 31542552
211 + 31542341 = 31542552

Showing the first eight; more decompositions exist.
