Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501694, here are decompositions:

61 + 31501633 = 31501694
73 + 31501621 = 31501694
127 + 31501567 = 31501694
157 + 31501537 = 31501694
163 + 31501531 = 31501694
307 + 31501387 = 31501694
373 + 31501321 = 31501694
463 + 31501231 = 31501694

Showing the first eight; more decompositions exist.
