Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009402, here are decompositions:

3 + 1009399 = 1009402
29 + 1009373 = 1009402
41 + 1009361 = 1009402
59 + 1009343 = 1009402
83 + 1009319 = 1009402
101 + 1009301 = 1009402
113 + 1009289 = 1009402
239 + 1009163 = 1009402

Showing the first eight; more decompositions exist.
