Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472370, here are decompositions:

11 + 31472359 = 31472370
19 + 31472351 = 31472370
31 + 31472339 = 31472370
79 + 31472291 = 31472370
109 + 31472261 = 31472370
131 + 31472239 = 31472370
179 + 31472191 = 31472370
191 + 31472179 = 31472370

Showing the first eight; more decompositions exist.
