Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527814, here are decompositions:

113 + 31527701 = 31527814
137 + 31527677 = 31527814
281 + 31527533 = 31527814
293 + 31527521 = 31527814
317 + 31527497 = 31527814
401 + 31527413 = 31527814
491 + 31527323 = 31527814
503 + 31527311 = 31527814

Showing the first eight; more decompositions exist.
