Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460372, here are decompositions:

3 + 31460369 = 31460372
43 + 31460329 = 31460372
79 + 31460293 = 31460372
109 + 31460263 = 31460372
199 + 31460173 = 31460372
373 + 31459999 = 31460372
379 + 31459993 = 31460372
409 + 31459963 = 31460372

Showing the first eight; more decompositions exist.
