Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489552, here are decompositions:

11 + 31489541 = 31489552
89 + 31489463 = 31489552
293 + 31489259 = 31489552
359 + 31489193 = 31489552
383 + 31489169 = 31489552
461 + 31489091 = 31489552
509 + 31489043 = 31489552
593 + 31488959 = 31489552

Showing the first eight; more decompositions exist.
