Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456586, here are decompositions:

157 + 31456429 = 31456586
307 + 31456279 = 31456586
349 + 31456237 = 31456586
367 + 31456219 = 31456586
463 + 31456123 = 31456586
487 + 31456099 = 31456586
709 + 31455877 = 31456586
727 + 31455859 = 31456586

Showing the first eight; more decompositions exist.
