Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561250, here are decompositions:

59 + 561191 = 561250
89 + 561161 = 561250
149 + 561101 = 561250
167 + 561083 = 561250
191 + 561059 = 561250
197 + 561053 = 561250
281 + 560969 = 561250
311 + 560939 = 561250

Showing the first eight; more decompositions exist.
