Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039520, here are decompositions:

3 + 1039517 = 1039520
7 + 1039513 = 1039520
43 + 1039477 = 1039520
193 + 1039327 = 1039520
199 + 1039321 = 1039520
241 + 1039279 = 1039520
271 + 1039249 = 1039520
367 + 1039153 = 1039520

Showing the first eight; more decompositions exist.
