Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187470, here are decompositions:

7 + 187463 = 187470
29 + 187441 = 187470
37 + 187433 = 187470
47 + 187423 = 187470
53 + 187417 = 187470
61 + 187409 = 187470
83 + 187387 = 187470
97 + 187373 = 187470

Showing the first eight; more decompositions exist.
