Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001550, here are decompositions:

19 + 1001531 = 1001550
23 + 1001527 = 1001550
59 + 1001491 = 1001550
83 + 1001467 = 1001550
103 + 1001447 = 1001550
139 + 1001411 = 1001550
149 + 1001401 = 1001550
163 + 1001387 = 1001550

Showing the first eight; more decompositions exist.
