Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152142, here are decompositions:

19 + 152123 = 152142
31 + 152111 = 152142
59 + 152083 = 152142
61 + 152081 = 152142
79 + 152063 = 152142
101 + 152041 = 152142
103 + 152039 = 152142
113 + 152029 = 152142

Showing the first eight; more decompositions exist.
