Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587060, here are decompositions:

7 + 31587053 = 31587060
31 + 31587029 = 31587060
41 + 31587019 = 31587060
139 + 31586921 = 31587060
157 + 31586903 = 31587060
181 + 31586879 = 31587060
191 + 31586869 = 31587060
251 + 31586809 = 31587060

Showing the first eight; more decompositions exist.
