Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72242, here are decompositions:

13 + 72229 = 72242
19 + 72223 = 72242
31 + 72211 = 72242
73 + 72169 = 72242
103 + 72139 = 72242
139 + 72103 = 72242
151 + 72091 = 72242
199 + 72043 = 72242

Showing the first eight; more decompositions exist.
