Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152042, here are decompositions:

3 + 152039 = 152042
13 + 152029 = 152042
73 + 151969 = 152042
103 + 151939 = 152042
139 + 151903 = 152042
193 + 151849 = 152042
229 + 151813 = 152042
271 + 151771 = 152042

Showing the first eight; more decompositions exist.
