Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586834, here are decompositions:

31 + 31586803 = 31586834
43 + 31586791 = 31586834
127 + 31586707 = 31586834
163 + 31586671 = 31586834
337 + 31586497 = 31586834
373 + 31586461 = 31586834
457 + 31586377 = 31586834
523 + 31586311 = 31586834

Showing the first eight; more decompositions exist.
