Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587058, here are decompositions:

5 + 31587053 = 31587058
29 + 31587029 = 31587058
131 + 31586927 = 31587058
137 + 31586921 = 31587058
179 + 31586879 = 31587058
359 + 31586699 = 31587058
389 + 31586669 = 31587058
431 + 31586627 = 31587058

Showing the first eight; more decompositions exist.
