Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525086, here are decompositions:

43 + 525043 = 525086
73 + 525013 = 525086
103 + 524983 = 525086
127 + 524959 = 525086
139 + 524947 = 525086
193 + 524893 = 525086
223 + 524863 = 525086
229 + 524857 = 525086

Showing the first eight; more decompositions exist.
