Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493242, here are decompositions:

11 + 493231 = 493242
23 + 493219 = 493242
31 + 493211 = 493242
41 + 493201 = 493242
73 + 493169 = 493242
83 + 493159 = 493242
103 + 493139 = 493242
109 + 493133 = 493242

Showing the first eight; more decompositions exist.
