Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468244, here are decompositions:

13 + 31468231 = 31468244
43 + 31468201 = 31468244
97 + 31468147 = 31468244
277 + 31467967 = 31468244
307 + 31467937 = 31468244
397 + 31467847 = 31468244
433 + 31467811 = 31468244
523 + 31467721 = 31468244

Showing the first eight; more decompositions exist.
