Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576552, here are decompositions:

3 + 31576549 = 31576552
11 + 31576541 = 31576552
23 + 31576529 = 31576552
41 + 31576511 = 31576552
113 + 31576439 = 31576552
149 + 31576403 = 31576552
179 + 31576373 = 31576552
263 + 31576289 = 31576552

Showing the first eight; more decompositions exist.
