Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462508, here are decompositions:

37 + 31462471 = 31462508
67 + 31462441 = 31462508
127 + 31462381 = 31462508
151 + 31462357 = 31462508
157 + 31462351 = 31462508
241 + 31462267 = 31462508
367 + 31462141 = 31462508
439 + 31462069 = 31462508

Showing the first eight; more decompositions exist.
