Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507652, here are decompositions:

19 + 31507633 = 31507652
61 + 31507591 = 31507652
79 + 31507573 = 31507652
193 + 31507459 = 31507652
331 + 31507321 = 31507652
409 + 31507243 = 31507652
571 + 31507081 = 31507652
643 + 31507009 = 31507652

Showing the first eight; more decompositions exist.
