Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523804, here are decompositions:

3 + 31523801 = 31523804
43 + 31523761 = 31523804
97 + 31523707 = 31523804
157 + 31523647 = 31523804
283 + 31523521 = 31523804
331 + 31523473 = 31523804
337 + 31523467 = 31523804
397 + 31523407 = 31523804

Showing the first eight; more decompositions exist.
