Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001770, here are decompositions:

47 + 1001723 = 1001770
83 + 1001687 = 1001770
101 + 1001669 = 1001770
131 + 1001639 = 1001770
149 + 1001621 = 1001770
239 + 1001531 = 1001770
269 + 1001501 = 1001770
311 + 1001459 = 1001770

Showing the first eight; more decompositions exist.
