Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 553390, here are decompositions:

113 + 553277 = 553390
137 + 553253 = 553390
179 + 553211 = 553390
197 + 553193 = 553390
251 + 553139 = 553390
293 + 553097 = 553390
317 + 553073 = 553390
347 + 553043 = 553390

Showing the first eight; more decompositions exist.
