Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592698, here are decompositions:

47 + 31592651 = 31592698
131 + 31592567 = 31592698
167 + 31592531 = 31592698
251 + 31592447 = 31592698
281 + 31592417 = 31592698
479 + 31592219 = 31592698
569 + 31592129 = 31592698
647 + 31592051 = 31592698

Showing the first eight; more decompositions exist.
