Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531130, here are decompositions:

29 + 531101 = 531130
59 + 531071 = 531130
107 + 531023 = 531130
113 + 531017 = 531130
233 + 530897 = 531130
269 + 530861 = 531130
293 + 530837 = 531130
389 + 530741 = 531130

Showing the first eight; more decompositions exist.
