Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523626, here are decompositions:

47 + 31523579 = 31523626
89 + 31523537 = 31523626
149 + 31523477 = 31523626
227 + 31523399 = 31523626
317 + 31523309 = 31523626
347 + 31523279 = 31523626
359 + 31523267 = 31523626
383 + 31523243 = 31523626

Showing the first eight; more decompositions exist.
