Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527282, here are decompositions:

5 + 31527277 = 31527282
29 + 31527253 = 31527282
71 + 31527211 = 31527282
89 + 31527193 = 31527282
109 + 31527173 = 31527282
131 + 31527151 = 31527282
139 + 31527143 = 31527282
151 + 31527131 = 31527282

Showing the first eight; more decompositions exist.
