Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541036, here are decompositions:

19 + 31541017 = 31541036
97 + 31540939 = 31541036
199 + 31540837 = 31541036
223 + 31540813 = 31541036
313 + 31540723 = 31541036
337 + 31540699 = 31541036
367 + 31540669 = 31541036
379 + 31540657 = 31541036

Showing the first eight; more decompositions exist.
