Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501964, here are decompositions:

7 + 31501957 = 31501964
103 + 31501861 = 31501964
157 + 31501807 = 31501964
223 + 31501741 = 31501964
331 + 31501633 = 31501964
397 + 31501567 = 31501964
433 + 31501531 = 31501964
577 + 31501387 = 31501964

Showing the first eight; more decompositions exist.
