Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462434, here are decompositions:

53 + 31462381 = 31462434
61 + 31462373 = 31462434
71 + 31462363 = 31462434
83 + 31462351 = 31462434
167 + 31462267 = 31462434
293 + 31462141 = 31462434
307 + 31462127 = 31462434
331 + 31462103 = 31462434

Showing the first eight; more decompositions exist.
