Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592632, here are decompositions:

11 + 31592621 = 31592632
101 + 31592531 = 31592632
179 + 31592453 = 31592632
263 + 31592369 = 31592632
419 + 31592213 = 31592632
503 + 31592129 = 31592632
509 + 31592123 = 31592632
593 + 31592039 = 31592632

Showing the first eight; more decompositions exist.
