Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018172, here are decompositions:

151 + 1018021 = 1018172
283 + 1017889 = 1018172
313 + 1017859 = 1018172
373 + 1017799 = 1018172
499 + 1017673 = 1018172
523 + 1017649 = 1018172
613 + 1017559 = 1018172
619 + 1017553 = 1018172

Showing the first eight; more decompositions exist.
