Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527802, here are decompositions:

101 + 31527701 = 31527802
113 + 31527689 = 31527802
233 + 31527569 = 31527802
269 + 31527533 = 31527802
281 + 31527521 = 31527802
311 + 31527491 = 31527802
389 + 31527413 = 31527802
479 + 31527323 = 31527802

Showing the first eight; more decompositions exist.
