Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527350, here are decompositions:

7 + 31527343 = 31527350
73 + 31527277 = 31527350
97 + 31527253 = 31527350
103 + 31527247 = 31527350
139 + 31527211 = 31527350
157 + 31527193 = 31527350
193 + 31527157 = 31527350
199 + 31527151 = 31527350

Showing the first eight; more decompositions exist.
