Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617254, here are decompositions:

3 + 31617251 = 31617254
73 + 31617181 = 31617254
181 + 31617073 = 31617254
241 + 31617013 = 31617254
337 + 31616917 = 31617254
367 + 31616887 = 31617254
397 + 31616857 = 31617254
547 + 31616707 = 31617254

Showing the first eight; more decompositions exist.
