Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619496, here are decompositions:

37 + 31619459 = 31619496
89 + 31619407 = 31619496
107 + 31619389 = 31619496
109 + 31619387 = 31619496
137 + 31619359 = 31619496
229 + 31619267 = 31619496
239 + 31619257 = 31619496
283 + 31619213 = 31619496

Showing the first eight; more decompositions exist.
