Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161602, here are decompositions:

3 + 161599 = 161602
11 + 161591 = 161602
29 + 161573 = 161602
41 + 161561 = 161602
59 + 161543 = 161602
71 + 161531 = 161602
131 + 161471 = 161602
149 + 161453 = 161602

Showing the first eight; more decompositions exist.
