Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10402, here are decompositions:

3 + 10399 = 10402
11 + 10391 = 10402
59 + 10343 = 10402
71 + 10331 = 10402
89 + 10313 = 10402
101 + 10301 = 10402
113 + 10289 = 10402
131 + 10271 = 10402

Showing the first eight; more decompositions exist.
