Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592802, here are decompositions:

5 + 31592797 = 31592802
23 + 31592779 = 31592802
29 + 31592773 = 31592802
41 + 31592761 = 31592802
139 + 31592663 = 31592802
151 + 31592651 = 31592802
181 + 31592621 = 31592802
251 + 31592551 = 31592802

Showing the first eight; more decompositions exist.
