Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70140, here are decompositions:

17 + 70123 = 70140
19 + 70121 = 70140
23 + 70117 = 70140
29 + 70111 = 70140
41 + 70099 = 70140
61 + 70079 = 70140
73 + 70067 = 70140
79 + 70061 = 70140

Showing the first eight; more decompositions exist.
