Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526258, here are decompositions:

59 + 526199 = 526258
101 + 526157 = 526258
137 + 526121 = 526258
191 + 526067 = 526258
311 + 525947 = 526258
389 + 525869 = 526258
419 + 525839 = 526258
449 + 525809 = 526258

Showing the first eight; more decompositions exist.
