Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47778, here are decompositions:

37 + 47741 = 47778
41 + 47737 = 47778
61 + 47717 = 47778
67 + 47711 = 47778
79 + 47699 = 47778
97 + 47681 = 47778
139 + 47639 = 47778
149 + 47629 = 47778

Showing the first eight; more decompositions exist.
