Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564526, here are decompositions:

67 + 31564459 = 31564526
79 + 31564447 = 31564526
139 + 31564387 = 31564526
193 + 31564333 = 31564526
199 + 31564327 = 31564526
277 + 31564249 = 31564526
283 + 31564243 = 31564526
379 + 31564147 = 31564526

Showing the first eight; more decompositions exist.
