Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18470, here are decompositions:

13 + 18457 = 18470
19 + 18451 = 18470
31 + 18439 = 18470
37 + 18433 = 18470
43 + 18427 = 18470
73 + 18397 = 18470
103 + 18367 = 18470
157 + 18313 = 18470

Showing the first eight; more decompositions exist.
