Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468274, here are decompositions:

3 + 31468271 = 31468274
31 + 31468243 = 31468274
43 + 31468231 = 31468274
73 + 31468201 = 31468274
127 + 31468147 = 31468274
307 + 31467967 = 31468274
337 + 31467937 = 31468274
421 + 31467853 = 31468274

Showing the first eight; more decompositions exist.
