Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579484, here are decompositions:

3 + 31579481 = 31579484
7 + 31579477 = 31579484
31 + 31579453 = 31579484
37 + 31579447 = 31579484
73 + 31579411 = 31579484
127 + 31579357 = 31579484
163 + 31579321 = 31579484
193 + 31579291 = 31579484

Showing the first eight; more decompositions exist.
