Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003648, here are decompositions:

17 + 1003631 = 1003648
29 + 1003619 = 1003648
47 + 1003601 = 1003648
59 + 1003589 = 1003648
131 + 1003517 = 1003648
179 + 1003469 = 1003648
251 + 1003397 = 1003648
281 + 1003367 = 1003648

Showing the first eight; more decompositions exist.
