Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945872, here are decompositions:

61 + 945811 = 945872
73 + 945799 = 945872
139 + 945733 = 945872
199 + 945673 = 945872
241 + 945631 = 945872
271 + 945601 = 945872
283 + 945589 = 945872
409 + 945463 = 945872

Showing the first eight; more decompositions exist.
