Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500794, here are decompositions:

103 + 31500691 = 31500794
307 + 31500487 = 31500794
331 + 31500463 = 31500794
337 + 31500457 = 31500794
433 + 31500361 = 31500794
601 + 31500193 = 31500794
607 + 31500187 = 31500794
991 + 31499803 = 31500794

Showing the first eight; more decompositions exist.
