Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488778, here are decompositions:

19 + 488759 = 488778
29 + 488749 = 488778
61 + 488717 = 488778
67 + 488711 = 488778
89 + 488689 = 488778
127 + 488651 = 488778
137 + 488641 = 488778
139 + 488639 = 488778

Showing the first eight; more decompositions exist.
