Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619246, here are decompositions:

37 + 31619209 = 31619246
67 + 31619179 = 31619246
103 + 31619143 = 31619246
229 + 31619017 = 31619246
349 + 31618897 = 31619246
367 + 31618879 = 31619246
397 + 31618849 = 31619246
577 + 31618669 = 31619246

Showing the first eight; more decompositions exist.
