Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90778, here are decompositions:

29 + 90749 = 90778
47 + 90731 = 90778
101 + 90677 = 90778
131 + 90647 = 90778
137 + 90641 = 90778
179 + 90599 = 90778
251 + 90527 = 90778
419 + 90359 = 90778

Showing the first eight; more decompositions exist.
