Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561340, here are decompositions:

89 + 561251 = 561340
149 + 561191 = 561340
167 + 561173 = 561340
179 + 561161 = 561340
239 + 561101 = 561340
257 + 561083 = 561340
281 + 561059 = 561340
293 + 561047 = 561340

Showing the first eight; more decompositions exist.
