Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523838, here are decompositions:

37 + 31523801 = 31523838
89 + 31523749 = 31523838
131 + 31523707 = 31523838
179 + 31523659 = 31523838
191 + 31523647 = 31523838
239 + 31523599 = 31523838
317 + 31523521 = 31523838
397 + 31523441 = 31523838

Showing the first eight; more decompositions exist.
