Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 937890, here are decompositions:

7 + 937883 = 937890
13 + 937877 = 937890
43 + 937847 = 937890
67 + 937823 = 937890
71 + 937819 = 937890
89 + 937801 = 937890
101 + 937789 = 937890
113 + 937777 = 937890

Showing the first eight; more decompositions exist.
