Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592784, here are decompositions:

5 + 31592779 = 31592784
11 + 31592773 = 31592784
23 + 31592761 = 31592784
37 + 31592747 = 31592784
101 + 31592683 = 31592784
107 + 31592677 = 31592784
163 + 31592621 = 31592784
227 + 31592557 = 31592784

Showing the first eight; more decompositions exist.
