Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488830, here are decompositions:

3 + 488827 = 488830
71 + 488759 = 488830
101 + 488729 = 488830
107 + 488723 = 488830
113 + 488717 = 488830
179 + 488651 = 488830
191 + 488639 = 488830
197 + 488633 = 488830

Showing the first eight; more decompositions exist.
