Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492562, here are decompositions:

109 + 31492453 = 31492562
139 + 31492423 = 31492562
163 + 31492399 = 31492562
193 + 31492369 = 31492562
349 + 31492213 = 31492562
769 + 31491793 = 31492562
883 + 31491679 = 31492562
991 + 31491571 = 31492562

Showing the first eight; more decompositions exist.
