Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045342, here are decompositions:

101 + 1045241 = 1045342
113 + 1045229 = 1045342
149 + 1045193 = 1045342
191 + 1045151 = 1045342
281 + 1045061 = 1045342
401 + 1044941 = 1045342
449 + 1044893 = 1045342
491 + 1044851 = 1045342

Showing the first eight; more decompositions exist.
