Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 530172, here are decompositions:

29 + 530143 = 530172
43 + 530129 = 530172
79 + 530093 = 530172
109 + 530063 = 530172
131 + 530041 = 530172
151 + 530021 = 530172
173 + 529999 = 530172
191 + 529981 = 530172

Showing the first eight; more decompositions exist.
