Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011530, here are decompositions:

139 + 1011391 = 1011530
181 + 1011349 = 1011530
199 + 1011331 = 1011530
241 + 1011289 = 1011530
313 + 1011217 = 1011530
367 + 1011163 = 1011530
439 + 1011091 = 1011530
463 + 1011067 = 1011530

Showing the first eight; more decompositions exist.
