Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130372, here are decompositions:

3 + 130369 = 130372
5 + 130367 = 130372
23 + 130349 = 130372
29 + 130343 = 130372
113 + 130259 = 130372
131 + 130241 = 130372
149 + 130223 = 130372
173 + 130199 = 130372

Showing the first eight; more decompositions exist.
