Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021402, here are decompositions:

29 + 1021373 = 1021402
71 + 1021331 = 1021402
101 + 1021301 = 1021402
113 + 1021289 = 1021402
131 + 1021271 = 1021402
149 + 1021253 = 1021402
311 + 1021091 = 1021402
359 + 1021043 = 1021402

Showing the first eight; more decompositions exist.
