Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479552, here are decompositions:

11 + 31479541 = 31479552
53 + 31479499 = 31479552
61 + 31479491 = 31479552
113 + 31479439 = 31479552
131 + 31479421 = 31479552
263 + 31479289 = 31479552
281 + 31479271 = 31479552
283 + 31479269 = 31479552

Showing the first eight; more decompositions exist.
