Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987374, here are decompositions:

13 + 987361 = 987374
61 + 987313 = 987374
163 + 987211 = 987374
181 + 987193 = 987374
277 + 987097 = 987374
307 + 987067 = 987374
313 + 987061 = 987374
331 + 987043 = 987374

Showing the first eight; more decompositions exist.
