Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026542, here are decompositions:

61 + 1026481 = 1026542
103 + 1026439 = 1026542
151 + 1026391 = 1026542
211 + 1026331 = 1026542
229 + 1026313 = 1026542
313 + 1026229 = 1026542
499 + 1026043 = 1026542
613 + 1025929 = 1026542

Showing the first eight; more decompositions exist.
