Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531418, here are decompositions:

59 + 531359 = 531418
71 + 531347 = 531418
131 + 531287 = 531418
137 + 531281 = 531418
179 + 531239 = 531418
317 + 531101 = 531418
347 + 531071 = 531418
401 + 531017 = 531418

Showing the first eight; more decompositions exist.
