Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606970, here are decompositions:

7 + 31606963 = 31606970
13 + 31606957 = 31606970
19 + 31606951 = 31606970
67 + 31606903 = 31606970
229 + 31606741 = 31606970
313 + 31606657 = 31606970
433 + 31606537 = 31606970
541 + 31606429 = 31606970

Showing the first eight; more decompositions exist.
