Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472430, here are decompositions:

71 + 31472359 = 31472430
79 + 31472351 = 31472430
137 + 31472293 = 31472430
139 + 31472291 = 31472430
191 + 31472239 = 31472430
229 + 31472201 = 31472430
239 + 31472191 = 31472430
251 + 31472179 = 31472430

Showing the first eight; more decompositions exist.
