Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981746, here are decompositions:

43 + 981703 = 981746
109 + 981637 = 981746
223 + 981523 = 981746
229 + 981517 = 981746
307 + 981439 = 981746
349 + 981397 = 981746
373 + 981373 = 981746
457 + 981289 = 981746

Showing the first eight; more decompositions exist.
