Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465976, here are decompositions:

97 + 31465879 = 31465976
127 + 31465849 = 31465976
229 + 31465747 = 31465976
313 + 31465663 = 31465976
397 + 31465579 = 31465976
613 + 31465363 = 31465976
733 + 31465243 = 31465976
823 + 31465153 = 31465976

Showing the first eight; more decompositions exist.
