Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515622, here are decompositions:

11 + 515611 = 515622
43 + 515579 = 515622
59 + 515563 = 515622
83 + 515539 = 515622
103 + 515519 = 515622
193 + 515429 = 515622
241 + 515381 = 515622
251 + 515371 = 515622

Showing the first eight; more decompositions exist.
