Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015772, here are decompositions:

3 + 1015769 = 1015772
19 + 1015753 = 1015772
211 + 1015561 = 1015772
223 + 1015549 = 1015772
271 + 1015501 = 1015772
313 + 1015459 = 1015772
349 + 1015423 = 1015772
409 + 1015363 = 1015772

Showing the first eight; more decompositions exist.
