Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460258, here are decompositions:

61 + 31460197 = 31460258
241 + 31460017 = 31460258
367 + 31459891 = 31460258
409 + 31459849 = 31460258
499 + 31459759 = 31460258
541 + 31459717 = 31460258
607 + 31459651 = 31460258
859 + 31459399 = 31460258

Showing the first eight; more decompositions exist.
