Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564592, here are decompositions:

61 + 31564531 = 31564592
271 + 31564321 = 31564592
331 + 31564261 = 31564592
349 + 31564243 = 31564592
421 + 31564171 = 31564592
463 + 31564129 = 31564592
541 + 31564051 = 31564592
613 + 31563979 = 31564592

Showing the first eight; more decompositions exist.
