Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013198, here are decompositions:

157 + 1013041 = 1013198
337 + 1012861 = 1013198
367 + 1012831 = 1013198
409 + 1012789 = 1013198
499 + 1012699 = 1013198
541 + 1012657 = 1013198
601 + 1012597 = 1013198
607 + 1012591 = 1013198

Showing the first eight; more decompositions exist.
