Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454652, here are decompositions:

139 + 31454513 = 31454652
191 + 31454461 = 31454652
211 + 31454441 = 31454652
263 + 31454389 = 31454652
269 + 31454383 = 31454652
331 + 31454321 = 31454652
389 + 31454263 = 31454652
431 + 31454221 = 31454652

Showing the first eight; more decompositions exist.
