Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447604, here are decompositions:

31 + 31447573 = 31447604
127 + 31447477 = 31447604
163 + 31447441 = 31447604
211 + 31447393 = 31447604
241 + 31447363 = 31447604
271 + 31447333 = 31447604
337 + 31447267 = 31447604
523 + 31447081 = 31447604

Showing the first eight; more decompositions exist.
