Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462598, here are decompositions:

7 + 31462591 = 31462598
19 + 31462579 = 31462598
67 + 31462531 = 31462598
127 + 31462471 = 31462598
157 + 31462441 = 31462598
241 + 31462357 = 31462598
331 + 31462267 = 31462598
457 + 31462141 = 31462598

Showing the first eight; more decompositions exist.
