Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 937820, here are decompositions:

7 + 937813 = 937820
19 + 937801 = 937820
31 + 937789 = 937820
43 + 937777 = 937820
73 + 937747 = 937820
127 + 937693 = 937820
139 + 937681 = 937820
157 + 937663 = 937820

Showing the first eight; more decompositions exist.
