Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542348, here are decompositions:

7 + 31542341 = 31542348
67 + 31542281 = 31542348
151 + 31542197 = 31542348
199 + 31542149 = 31542348
281 + 31542067 = 31542348
311 + 31542037 = 31542348
317 + 31542031 = 31542348
337 + 31542011 = 31542348

Showing the first eight; more decompositions exist.
