Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527438, here are decompositions:

31 + 31527407 = 31527438
127 + 31527311 = 31527438
191 + 31527247 = 31527438
227 + 31527211 = 31527438
281 + 31527157 = 31527438
307 + 31527131 = 31527438
331 + 31527107 = 31527438
421 + 31527017 = 31527438

Showing the first eight; more decompositions exist.
