Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015372, here are decompositions:

3 + 1015369 = 1015372
5 + 1015367 = 1015372
11 + 1015361 = 1015372
23 + 1015349 = 1015372
173 + 1015199 = 1015372
233 + 1015139 = 1015372
311 + 1015061 = 1015372
383 + 1014989 = 1015372

Showing the first eight; more decompositions exist.
