Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31587052, here are decompositions:

23 + 31587029 = 31587052
113 + 31586939 = 31587052
131 + 31586921 = 31587052
149 + 31586903 = 31587052
173 + 31586879 = 31587052
239 + 31586813 = 31587052
353 + 31586699 = 31587052
383 + 31586669 = 31587052

Showing the first eight; more decompositions exist.
