Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527462, here are decompositions:

73 + 31527389 = 31527462
139 + 31527323 = 31527462
151 + 31527311 = 31527462
229 + 31527233 = 31527462
251 + 31527211 = 31527462
269 + 31527193 = 31527462
271 + 31527191 = 31527462
311 + 31527151 = 31527462

Showing the first eight; more decompositions exist.
