Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37890, here are decompositions:

11 + 37879 = 37890
19 + 37871 = 37890
29 + 37861 = 37890
37 + 37853 = 37890
43 + 37847 = 37890
59 + 37831 = 37890
79 + 37811 = 37890
107 + 37783 = 37890

Showing the first eight; more decompositions exist.
