Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143370, here are decompositions:

13 + 143357 = 143370
37 + 143333 = 143370
41 + 143329 = 143370
79 + 143291 = 143370
83 + 143287 = 143370
89 + 143281 = 143370
107 + 143263 = 143370
109 + 143261 = 143370

Showing the first eight; more decompositions exist.
