Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463018, here are decompositions:

109 + 31462909 = 31463018
211 + 31462807 = 31463018
271 + 31462747 = 31463018
409 + 31462609 = 31463018
439 + 31462579 = 31463018
487 + 31462531 = 31463018
547 + 31462471 = 31463018
577 + 31462441 = 31463018

Showing the first eight; more decompositions exist.
