Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534618, here are decompositions:

29 + 31534589 = 31534618
131 + 31534487 = 31534618
191 + 31534427 = 31534618
317 + 31534301 = 31534618
347 + 31534271 = 31534618
419 + 31534199 = 31534618
431 + 31534187 = 31534618
449 + 31534169 = 31534618

Showing the first eight; more decompositions exist.
