Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89742, here are decompositions:

53 + 89689 = 89742
61 + 89681 = 89742
71 + 89671 = 89742
73 + 89669 = 89742
83 + 89659 = 89742
89 + 89653 = 89742
109 + 89633 = 89742
131 + 89611 = 89742

Showing the first eight; more decompositions exist.
