Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7874, here are decompositions:

7 + 7867 = 7874
151 + 7723 = 7874
157 + 7717 = 7874
193 + 7681 = 7874
271 + 7603 = 7874
283 + 7591 = 7874
313 + 7561 = 7874
337 + 7537 = 7874

Showing the first eight; more decompositions exist.
