Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588244, here are decompositions:

43 + 31588201 = 31588244
73 + 31588171 = 31588244
157 + 31588087 = 31588244
241 + 31588003 = 31588244
283 + 31587961 = 31588244
367 + 31587877 = 31588244
463 + 31587781 = 31588244
547 + 31587697 = 31588244

Showing the first eight; more decompositions exist.
