Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579852, here are decompositions:

89 + 31579763 = 31579852
113 + 31579739 = 31579852
131 + 31579721 = 31579852
149 + 31579703 = 31579852
191 + 31579661 = 31579852
233 + 31579619 = 31579852
383 + 31579469 = 31579852
509 + 31579343 = 31579852

Showing the first eight; more decompositions exist.
