Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579174, here are decompositions:

41 + 31579133 = 31579174
47 + 31579127 = 31579174
71 + 31579103 = 31579174
83 + 31579091 = 31579174
101 + 31579073 = 31579174
227 + 31578947 = 31579174
251 + 31578923 = 31579174
293 + 31578881 = 31579174

Showing the first eight; more decompositions exist.
