Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462232, here are decompositions:

163 + 31462069 = 31462232
211 + 31462021 = 31462232
229 + 31462003 = 31462232
271 + 31461961 = 31462232
283 + 31461949 = 31462232
313 + 31461919 = 31462232
409 + 31461823 = 31462232
421 + 31461811 = 31462232

Showing the first eight; more decompositions exist.
