Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564796, here are decompositions:

73 + 31564723 = 31564796
127 + 31564669 = 31564796
139 + 31564657 = 31564796
157 + 31564639 = 31564796
337 + 31564459 = 31564796
349 + 31564447 = 31564796
409 + 31564387 = 31564796
463 + 31564333 = 31564796

Showing the first eight; more decompositions exist.
