Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535750, here are decompositions:

3 + 31535747 = 31535750
79 + 31535671 = 31535750
157 + 31535593 = 31535750
199 + 31535551 = 31535750
283 + 31535467 = 31535750
331 + 31535419 = 31535750
373 + 31535377 = 31535750
409 + 31535341 = 31535750

Showing the first eight; more decompositions exist.
