Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542434, here are decompositions:

37 + 31542397 = 31542434
43 + 31542391 = 31542434
61 + 31542373 = 31542434
271 + 31542163 = 31542434
331 + 31542103 = 31542434
367 + 31542067 = 31542434
397 + 31542037 = 31542434
421 + 31542013 = 31542434

Showing the first eight; more decompositions exist.
