Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466542, here are decompositions:

251 + 31466291 = 31466542
293 + 31466249 = 31466542
479 + 31466063 = 31466542
491 + 31466051 = 31466542
563 + 31465979 = 31466542
761 + 31465781 = 31466542
881 + 31465661 = 31466542
911 + 31465631 = 31466542

Showing the first eight; more decompositions exist.
