Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460438, here are decompositions:

7 + 31460431 = 31460438
109 + 31460329 = 31460438
157 + 31460281 = 31460438
241 + 31460197 = 31460438
271 + 31460167 = 31460438
421 + 31460017 = 31460438
439 + 31459999 = 31460438
547 + 31459891 = 31460438

Showing the first eight; more decompositions exist.
