Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558852, here are decompositions:

5 + 31558847 = 31558852
29 + 31558823 = 31558852
53 + 31558799 = 31558852
179 + 31558673 = 31558852
233 + 31558619 = 31558852
383 + 31558469 = 31558852
389 + 31558463 = 31558852
419 + 31558433 = 31558852

Showing the first eight; more decompositions exist.
