Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462502, here are decompositions:

31 + 31462471 = 31462502
61 + 31462441 = 31462502
139 + 31462363 = 31462502
151 + 31462351 = 31462502
163 + 31462339 = 31462502
229 + 31462273 = 31462502
433 + 31462069 = 31462502
499 + 31462003 = 31462502

Showing the first eight; more decompositions exist.
