Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024138, here are decompositions:

47 + 1024091 = 1024138
107 + 1024031 = 1024138
191 + 1023947 = 1024138
197 + 1023941 = 1024138
281 + 1023857 = 1024138
317 + 1023821 = 1024138
419 + 1023719 = 1024138
587 + 1023551 = 1024138

Showing the first eight; more decompositions exist.
