Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619608, here are decompositions:

5 + 31619603 = 31619608
47 + 31619561 = 31619608
89 + 31619519 = 31619608
107 + 31619501 = 31619608
149 + 31619459 = 31619608
281 + 31619327 = 31619608
347 + 31619261 = 31619608
401 + 31619207 = 31619608

Showing the first eight; more decompositions exist.
