Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527394, here are decompositions:

5 + 31527389 = 31527394
71 + 31527323 = 31527394
83 + 31527311 = 31527394
251 + 31527143 = 31527394
263 + 31527131 = 31527394
317 + 31527077 = 31527394
347 + 31527047 = 31527394
383 + 31527011 = 31527394

Showing the first eight; more decompositions exist.
