Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534136, here are decompositions:

19 + 31534117 = 31534136
79 + 31534057 = 31534136
103 + 31534033 = 31534136
157 + 31533979 = 31534136
307 + 31533829 = 31534136
313 + 31533823 = 31534136
367 + 31533769 = 31534136
373 + 31533763 = 31534136

Showing the first eight; more decompositions exist.
