Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015940, here are decompositions:

43 + 1015897 = 1015940
97 + 1015843 = 1015940
127 + 1015813 = 1015940
193 + 1015747 = 1015940
313 + 1015627 = 1015940
337 + 1015603 = 1015940
379 + 1015561 = 1015940
433 + 1015507 = 1015940

Showing the first eight; more decompositions exist.
