Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057820, here are decompositions:

13 + 1057807 = 1057820
67 + 1057753 = 1057820
79 + 1057741 = 1057820
139 + 1057681 = 1057820
157 + 1057663 = 1057820
163 + 1057657 = 1057820
241 + 1057579 = 1057820
331 + 1057489 = 1057820

Showing the first eight; more decompositions exist.
