Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618424, here are decompositions:

127 + 31618297 = 31618424
193 + 31618231 = 31618424
367 + 31618057 = 31618424
421 + 31618003 = 31618424
457 + 31617967 = 31618424
463 + 31617961 = 31618424
547 + 31617877 = 31618424
571 + 31617853 = 31618424

Showing the first eight; more decompositions exist.
