Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615976, here are decompositions:

3 + 31615973 = 31615976
127 + 31615849 = 31615976
193 + 31615783 = 31615976
307 + 31615669 = 31615976
313 + 31615663 = 31615976
367 + 31615609 = 31615976
373 + 31615603 = 31615976
433 + 31615543 = 31615976

Showing the first eight; more decompositions exist.
