Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592434, here are decompositions:

11 + 31592423 = 31592434
17 + 31592417 = 31592434
23 + 31592411 = 31592434
311 + 31592123 = 31592434
383 + 31592051 = 31592434
521 + 31591913 = 31592434
641 + 31591793 = 31592434
683 + 31591751 = 31592434

Showing the first eight; more decompositions exist.
