Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540910, here are decompositions:

43 + 31540867 = 31540910
73 + 31540837 = 31540910
97 + 31540813 = 31540910
127 + 31540783 = 31540910
211 + 31540699 = 31540910
241 + 31540669 = 31540910
337 + 31540573 = 31540910
409 + 31540501 = 31540910

Showing the first eight; more decompositions exist.
