Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1049472, here are decompositions:

13 + 1049459 = 1049472
43 + 1049429 = 1049472
59 + 1049413 = 1049472
139 + 1049333 = 1049472
191 + 1049281 = 1049472
233 + 1049239 = 1049472
271 + 1049201 = 1049472
331 + 1049141 = 1049472

Showing the first eight; more decompositions exist.
