Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564462, here are decompositions:

3 + 31564459 = 31564462
23 + 31564439 = 31564462
29 + 31564433 = 31564462
71 + 31564391 = 31564462
101 + 31564361 = 31564462
131 + 31564331 = 31564462
191 + 31564271 = 31564462
233 + 31564229 = 31564462

Showing the first eight; more decompositions exist.
