Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461534, here are decompositions:

11 + 31461523 = 31461534
17 + 31461517 = 31461534
47 + 31461487 = 31461534
53 + 31461481 = 31461534
107 + 31461427 = 31461534
131 + 31461403 = 31461534
173 + 31461361 = 31461534
191 + 31461343 = 31461534

Showing the first eight; more decompositions exist.
