Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531448, here are decompositions:

89 + 531359 = 531448
101 + 531347 = 531448
149 + 531299 = 531448
167 + 531281 = 531448
251 + 531197 = 531448
347 + 531101 = 531448
431 + 531017 = 531448
479 + 530969 = 531448

Showing the first eight; more decompositions exist.
