Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487696, here are decompositions:

157 + 31487539 = 31487696
223 + 31487473 = 31487696
277 + 31487419 = 31487696
349 + 31487347 = 31487696
367 + 31487329 = 31487696
379 + 31487317 = 31487696
433 + 31487263 = 31487696
463 + 31487233 = 31487696

Showing the first eight; more decompositions exist.
