Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534330, here are decompositions:

29 + 31534301 = 31534330
59 + 31534271 = 31534330
83 + 31534247 = 31534330
89 + 31534241 = 31534330
131 + 31534199 = 31534330
227 + 31534103 = 31534330
251 + 31534079 = 31534330
257 + 31534073 = 31534330

Showing the first eight; more decompositions exist.
