Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527382, here are decompositions:

59 + 31527323 = 31527382
71 + 31527311 = 31527382
149 + 31527233 = 31527382
191 + 31527191 = 31527382
233 + 31527149 = 31527382
239 + 31527143 = 31527382
251 + 31527131 = 31527382
443 + 31526939 = 31527382

Showing the first eight; more decompositions exist.
