Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021360, here are decompositions:

29 + 1021331 = 1021360
59 + 1021301 = 1021360
71 + 1021289 = 1021360
89 + 1021271 = 1021360
101 + 1021259 = 1021360
107 + 1021253 = 1021360
233 + 1021127 = 1021360
269 + 1021091 = 1021360

Showing the first eight; more decompositions exist.
