Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2402, here are decompositions:

3 + 2399 = 2402
13 + 2389 = 2402
19 + 2383 = 2402
31 + 2371 = 2402
61 + 2341 = 2402
109 + 2293 = 2402
151 + 2251 = 2402
163 + 2239 = 2402

Showing the first eight; more decompositions exist.
