Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587048, here are decompositions:

19 + 31587029 = 31587048
29 + 31587019 = 31587048
107 + 31586941 = 31587048
109 + 31586939 = 31587048
127 + 31586921 = 31587048
179 + 31586869 = 31587048
239 + 31586809 = 31587048
257 + 31586791 = 31587048

Showing the first eight; more decompositions exist.
