Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65578, here are decompositions:

41 + 65537 = 65578
59 + 65519 = 65578
131 + 65447 = 65578
197 + 65381 = 65578
251 + 65327 = 65578
269 + 65309 = 65578
311 + 65267 = 65578
431 + 65147 = 65578

Showing the first eight; more decompositions exist.
