Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461448, here are decompositions:

107 + 31461341 = 31461448
167 + 31461281 = 31461448
257 + 31461191 = 31461448
269 + 31461179 = 31461448
401 + 31461047 = 31461448
521 + 31460927 = 31461448
569 + 31460879 = 31461448
617 + 31460831 = 31461448

Showing the first eight; more decompositions exist.
