Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564302, here are decompositions:

31 + 31564271 = 31564302
41 + 31564261 = 31564302
53 + 31564249 = 31564302
59 + 31564243 = 31564302
61 + 31564241 = 31564302
73 + 31564229 = 31564302
131 + 31564171 = 31564302
139 + 31564163 = 31564302

Showing the first eight; more decompositions exist.
