Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579496, here are decompositions:

19 + 31579477 = 31579496
43 + 31579453 = 31579496
97 + 31579399 = 31579496
103 + 31579393 = 31579496
139 + 31579357 = 31579496
283 + 31579213 = 31579496
367 + 31579129 = 31579496
397 + 31579099 = 31579496

Showing the first eight; more decompositions exist.
