Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535348, here are decompositions:

7 + 31535341 = 31535348
37 + 31535311 = 31535348
241 + 31535107 = 31535348
337 + 31535011 = 31535348
349 + 31534999 = 31535348
367 + 31534981 = 31535348
547 + 31534801 = 31535348
619 + 31534729 = 31535348

Showing the first eight; more decompositions exist.
