Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40236, here are decompositions:

5 + 40231 = 40236
23 + 40213 = 40236
43 + 40193 = 40236
47 + 40189 = 40236
59 + 40177 = 40236
67 + 40169 = 40236
73 + 40163 = 40236
83 + 40153 = 40236

Showing the first eight; more decompositions exist.
