Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4890, here are decompositions:

13 + 4877 = 4890
19 + 4871 = 4890
29 + 4861 = 4890
59 + 4831 = 4890
73 + 4817 = 4890
89 + 4801 = 4890
97 + 4793 = 4890
101 + 4789 = 4890

Showing the first eight; more decompositions exist.
