Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462448, here are decompositions:

7 + 31462441 = 31462448
67 + 31462381 = 31462448
97 + 31462351 = 31462448
109 + 31462339 = 31462448
181 + 31462267 = 31462448
307 + 31462141 = 31462448
379 + 31462069 = 31462448
487 + 31461961 = 31462448

Showing the first eight; more decompositions exist.
