Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615604, here are decompositions:

61 + 31615543 = 31615604
127 + 31615477 = 31615604
271 + 31615333 = 31615604
283 + 31615321 = 31615604
331 + 31615273 = 31615604
367 + 31615237 = 31615604
541 + 31615063 = 31615604
661 + 31614943 = 31615604

Showing the first eight; more decompositions exist.
