Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618612, here are decompositions:

149 + 31618463 = 31618612
251 + 31618361 = 31618612
293 + 31618319 = 31618612
401 + 31618211 = 31618612
419 + 31618193 = 31618612
449 + 31618163 = 31618612
479 + 31618133 = 31618612
491 + 31618121 = 31618612

Showing the first eight; more decompositions exist.
