Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70242, here are decompositions:

5 + 70237 = 70242
13 + 70229 = 70242
19 + 70223 = 70242
41 + 70201 = 70242
43 + 70199 = 70242
59 + 70183 = 70242
61 + 70181 = 70242
79 + 70163 = 70242

Showing the first eight; more decompositions exist.
