Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462652, here are decompositions:

3 + 31462649 = 31462652
43 + 31462609 = 31462652
61 + 31462591 = 31462652
73 + 31462579 = 31462652
79 + 31462573 = 31462652
181 + 31462471 = 31462652
211 + 31462441 = 31462652
271 + 31462381 = 31462652

Showing the first eight; more decompositions exist.
