Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31579062, here are decompositions:

23 + 31579039 = 31579062
59 + 31579003 = 31579062
89 + 31578973 = 31579062
113 + 31578949 = 31579062
139 + 31578923 = 31579062
181 + 31578881 = 31579062
241 + 31578821 = 31579062
271 + 31578791 = 31579062

Showing the first eight; more decompositions exist.
