Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514260, here are decompositions:

101 + 31514159 = 31514260
179 + 31514081 = 31514260
293 + 31513967 = 31514260
317 + 31513943 = 31514260
383 + 31513877 = 31514260
443 + 31513817 = 31514260
467 + 31513793 = 31514260
521 + 31513739 = 31514260

Showing the first eight; more decompositions exist.
