Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29240, here are decompositions:

19 + 29221 = 29240
31 + 29209 = 29240
61 + 29179 = 29240
67 + 29173 = 29240
73 + 29167 = 29240
103 + 29137 = 29240
109 + 29131 = 29240
139 + 29101 = 29240

Showing the first eight; more decompositions exist.
