Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451598, here are decompositions:

11 + 31451587 = 31451598
19 + 31451579 = 31451598
37 + 31451561 = 31451598
71 + 31451527 = 31451598
107 + 31451491 = 31451598
109 + 31451489 = 31451598
137 + 31451461 = 31451598
251 + 31451347 = 31451598

Showing the first eight; more decompositions exist.
