Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542452, here are decompositions:

13 + 31542439 = 31542452
61 + 31542391 = 31542452
79 + 31542373 = 31542452
223 + 31542229 = 31542452
349 + 31542103 = 31542452
421 + 31542031 = 31542452
439 + 31542013 = 31542452
463 + 31541989 = 31542452

Showing the first eight; more decompositions exist.
