Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015172, here are decompositions:

13 + 1015159 = 1015172
79 + 1015093 = 1015172
163 + 1015009 = 1015172
199 + 1014973 = 1015172
283 + 1014889 = 1015172
409 + 1014763 = 1015172
523 + 1014649 = 1015172
541 + 1014631 = 1015172

Showing the first eight; more decompositions exist.
