Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468304, here are decompositions:

61 + 31468243 = 31468304
73 + 31468231 = 31468304
103 + 31468201 = 31468304
157 + 31468147 = 31468304
277 + 31468027 = 31468304
337 + 31467967 = 31468304
367 + 31467937 = 31468304
457 + 31467847 = 31468304

Showing the first eight; more decompositions exist.
