Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477268, here are decompositions:

61 + 31477207 = 31477268
127 + 31477141 = 31477268
157 + 31477111 = 31477268
211 + 31477057 = 31477268
241 + 31477027 = 31477268
337 + 31476931 = 31477268
397 + 31476871 = 31477268
421 + 31476847 = 31477268

Showing the first eight; more decompositions exist.
