Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989242, here are decompositions:

3 + 989239 = 989242
11 + 989231 = 989242
71 + 989171 = 989242
263 + 988979 = 989242
383 + 988859 = 989242
479 + 988763 = 989242
509 + 988733 = 989242
593 + 988649 = 989242

Showing the first eight; more decompositions exist.
