Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42742, here are decompositions:

5 + 42737 = 42742
23 + 42719 = 42742
41 + 42701 = 42742
53 + 42689 = 42742
59 + 42683 = 42742
101 + 42641 = 42742
131 + 42611 = 42742
173 + 42569 = 42742

Showing the first eight; more decompositions exist.
