Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011788, here are decompositions:

139 + 1011649 = 1011788
157 + 1011631 = 1011788
199 + 1011589 = 1011788
229 + 1011559 = 1011788
397 + 1011391 = 1011788
439 + 1011349 = 1011788
457 + 1011331 = 1011788
499 + 1011289 = 1011788

Showing the first eight; more decompositions exist.
