Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618546, here are decompositions:

83 + 31618463 = 31618546
137 + 31618409 = 31618546
227 + 31618319 = 31618546
257 + 31618289 = 31618546
347 + 31618199 = 31618546
353 + 31618193 = 31618546
359 + 31618187 = 31618546
383 + 31618163 = 31618546

Showing the first eight; more decompositions exist.
