Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494348, here are decompositions:

47 + 31494301 = 31494348
101 + 31494247 = 31494348
107 + 31494241 = 31494348
191 + 31494157 = 31494348
229 + 31494119 = 31494348
251 + 31494097 = 31494348
257 + 31494091 = 31494348
269 + 31494079 = 31494348

Showing the first eight; more decompositions exist.
