Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003780, here are decompositions:

17 + 1003763 = 1003780
23 + 1003757 = 1003780
47 + 1003733 = 1003780
101 + 1003679 = 1003780
149 + 1003631 = 1003780
179 + 1003601 = 1003780
191 + 1003589 = 1003780
263 + 1003517 = 1003780

Showing the first eight; more decompositions exist.
