Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592852, here are decompositions:

3 + 31592849 = 31592852
19 + 31592833 = 31592852
43 + 31592809 = 31592852
73 + 31592779 = 31592852
79 + 31592773 = 31592852
211 + 31592641 = 31592852
463 + 31592389 = 31592852
541 + 31592311 = 31592852

Showing the first eight; more decompositions exist.
