Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011890, here are decompositions:

73 + 1011817 = 1011890
127 + 1011763 = 1011890
157 + 1011733 = 1011890
193 + 1011697 = 1011890
223 + 1011667 = 1011890
241 + 1011649 = 1011890
307 + 1011583 = 1011890
331 + 1011559 = 1011890

Showing the first eight; more decompositions exist.
