Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592754, here are decompositions:

7 + 31592747 = 31592754
71 + 31592683 = 31592754
103 + 31592651 = 31592754
113 + 31592641 = 31592754
197 + 31592557 = 31592754
223 + 31592531 = 31592754
307 + 31592447 = 31592754
317 + 31592437 = 31592754

Showing the first eight; more decompositions exist.
