Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564376, here are decompositions:

43 + 31564333 = 31564376
127 + 31564249 = 31564376
139 + 31564237 = 31564376
229 + 31564147 = 31564376
367 + 31564009 = 31564376
397 + 31563979 = 31564376
409 + 31563967 = 31564376
433 + 31563943 = 31564376

Showing the first eight; more decompositions exist.
