Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462748, here are decompositions:

19 + 31462729 = 31462748
139 + 31462609 = 31462748
157 + 31462591 = 31462748
241 + 31462507 = 31462748
277 + 31462471 = 31462748
307 + 31462441 = 31462748
367 + 31462381 = 31462748
397 + 31462351 = 31462748

Showing the first eight; more decompositions exist.
