Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542308, here are decompositions:

79 + 31542229 = 31542308
241 + 31542067 = 31542308
271 + 31542037 = 31542308
277 + 31542031 = 31542308
307 + 31542001 = 31542308
331 + 31541977 = 31542308
337 + 31541971 = 31542308
409 + 31541899 = 31542308

Showing the first eight; more decompositions exist.
