Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54778, here are decompositions:

5 + 54773 = 54778
11 + 54767 = 54778
131 + 54647 = 54778
149 + 54629 = 54778
197 + 54581 = 54778
239 + 54539 = 54778
257 + 54521 = 54778
281 + 54497 = 54778

Showing the first eight; more decompositions exist.
