Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535198, here are decompositions:

67 + 31535131 = 31535198
139 + 31535059 = 31535198
199 + 31534999 = 31535198
367 + 31534831 = 31535198
379 + 31534819 = 31535198
397 + 31534801 = 31535198
547 + 31534651 = 31535198
601 + 31534597 = 31535198

Showing the first eight; more decompositions exist.
