Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747342, here are decompositions:

13 + 8747329 = 8747342
151 + 8747191 = 8747342
223 + 8747119 = 8747342
271 + 8747071 = 8747342
379 + 8746963 = 8747342
421 + 8746921 = 8747342
463 + 8746879 = 8747342
523 + 8746819 = 8747342

Showing the first eight; more decompositions exist.
