Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162742, here are decompositions:

3 + 162739 = 162742
11 + 162731 = 162742
29 + 162713 = 162742
59 + 162683 = 162742
71 + 162671 = 162742
101 + 162641 = 162742
113 + 162629 = 162742
131 + 162611 = 162742

Showing the first eight; more decompositions exist.
