Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 578940, here are decompositions:

17 + 578923 = 578940
23 + 578917 = 578940
59 + 578881 = 578940
79 + 578861 = 578940
83 + 578857 = 578940
97 + 578843 = 578940
101 + 578839 = 578940
113 + 578827 = 578940

Showing the first eight; more decompositions exist.
