Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87260, here are decompositions:

3 + 87257 = 87260
7 + 87253 = 87260
37 + 87223 = 87260
73 + 87187 = 87260
79 + 87181 = 87260
109 + 87151 = 87260
127 + 87133 = 87260
139 + 87121 = 87260

Showing the first eight; more decompositions exist.
