Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470650, here are decompositions:

31 + 31470619 = 31470650
103 + 31470547 = 31470650
181 + 31470469 = 31470650
241 + 31470409 = 31470650
271 + 31470379 = 31470650
313 + 31470337 = 31470650
433 + 31470217 = 31470650
457 + 31470193 = 31470650

Showing the first eight; more decompositions exist.
