Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030742, here are decompositions:

3 + 1030739 = 1030742
19 + 1030723 = 1030742
61 + 1030681 = 1030742
103 + 1030639 = 1030742
199 + 1030543 = 1030742
313 + 1030429 = 1030742
331 + 1030411 = 1030742
373 + 1030369 = 1030742

Showing the first eight; more decompositions exist.
