Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462888, here are decompositions:

11 + 31462877 = 31462888
131 + 31462757 = 31462888
137 + 31462751 = 31462888
239 + 31462649 = 31462888
311 + 31462577 = 31462888
449 + 31462439 = 31462888
599 + 31462289 = 31462888
761 + 31462127 = 31462888

Showing the first eight; more decompositions exist.
