Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476430, here are decompositions:

17 + 31476413 = 31476430
47 + 31476383 = 31476430
59 + 31476371 = 31476430
113 + 31476317 = 31476430
179 + 31476251 = 31476430
191 + 31476239 = 31476430
281 + 31476149 = 31476430
311 + 31476119 = 31476430

Showing the first eight; more decompositions exist.
