Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013378, here are decompositions:

139 + 1013239 = 1013378
151 + 1013227 = 1013378
181 + 1013197 = 1013378
337 + 1013041 = 1013378
349 + 1013029 = 1013378
397 + 1012981 = 1013378
547 + 1012831 = 1013378
607 + 1012771 = 1013378

Showing the first eight; more decompositions exist.
