Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005542, here are decompositions:

61 + 1005481 = 1005542
103 + 1005439 = 1005542
151 + 1005391 = 1005542
193 + 1005349 = 1005542
211 + 1005331 = 1005542
229 + 1005313 = 1005542
313 + 1005229 = 1005542
409 + 1005133 = 1005542

Showing the first eight; more decompositions exist.
