Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619604, here are decompositions:

43 + 31619561 = 31619604
47 + 31619557 = 31619604
61 + 31619543 = 31619604
73 + 31619531 = 31619604
83 + 31619521 = 31619604
103 + 31619501 = 31619604
197 + 31619407 = 31619604
277 + 31619327 = 31619604

Showing the first eight; more decompositions exist.
