Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619836, here are decompositions:

29 + 31619807 = 31619836
47 + 31619789 = 31619836
113 + 31619723 = 31619836
167 + 31619669 = 31619836
233 + 31619603 = 31619836
293 + 31619543 = 31619836
317 + 31619519 = 31619836
449 + 31619387 = 31619836

Showing the first eight; more decompositions exist.
