Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619504, here are decompositions:

3 + 31619501 = 31619504
97 + 31619407 = 31619504
193 + 31619311 = 31619504
223 + 31619281 = 31619504
313 + 31619191 = 31619504
463 + 31619041 = 31619504
487 + 31619017 = 31619504
523 + 31618981 = 31619504

Showing the first eight; more decompositions exist.
