Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615834, here are decompositions:

71 + 31615763 = 31615834
251 + 31615583 = 31615834
431 + 31615403 = 31615834
443 + 31615391 = 31615834
491 + 31615343 = 31615834
521 + 31615313 = 31615834
617 + 31615217 = 31615834
641 + 31615193 = 31615834

Showing the first eight; more decompositions exist.
