Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579696, here are decompositions:

53 + 31579643 = 31579696
227 + 31579469 = 31579696
353 + 31579343 = 31579696
419 + 31579277 = 31579696
503 + 31579193 = 31579696
509 + 31579187 = 31579696
557 + 31579139 = 31579696
563 + 31579133 = 31579696

Showing the first eight; more decompositions exist.
