Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500266, here are decompositions:

3 + 31500263 = 31500266
73 + 31500193 = 31500266
79 + 31500187 = 31500266
277 + 31499989 = 31500266
367 + 31499899 = 31500266
373 + 31499893 = 31500266
433 + 31499833 = 31500266
463 + 31499803 = 31500266

Showing the first eight; more decompositions exist.
