Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021292, here are decompositions:

3 + 1021289 = 1021292
31 + 1021261 = 1021292
109 + 1021183 = 1021292
163 + 1021129 = 1021292
199 + 1021093 = 1021292
211 + 1021081 = 1021292
313 + 1020979 = 1021292
331 + 1020961 = 1021292

Showing the first eight; more decompositions exist.
