Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458552, here are decompositions:

11 + 31458541 = 31458552
71 + 31458481 = 31458552
101 + 31458451 = 31458552
149 + 31458403 = 31458552
173 + 31458379 = 31458552
179 + 31458373 = 31458552
241 + 31458311 = 31458552
313 + 31458239 = 31458552

Showing the first eight; more decompositions exist.
