Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88040, here are decompositions:

3 + 88037 = 88040
37 + 88003 = 88040
67 + 87973 = 88040
79 + 87961 = 88040
97 + 87943 = 88040
109 + 87931 = 88040
163 + 87877 = 88040
229 + 87811 = 88040

Showing the first eight; more decompositions exist.
