Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047812, here are decompositions:

61 + 1047751 = 1047812
109 + 1047703 = 1047812
163 + 1047649 = 1047812
223 + 1047589 = 1047812
313 + 1047499 = 1047812
421 + 1047391 = 1047812
433 + 1047379 = 1047812
439 + 1047373 = 1047812

Showing the first eight; more decompositions exist.
