Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462418, here are decompositions:

37 + 31462381 = 31462418
61 + 31462357 = 31462418
67 + 31462351 = 31462418
79 + 31462339 = 31462418
151 + 31462267 = 31462418
277 + 31462141 = 31462418
349 + 31462069 = 31462418
397 + 31462021 = 31462418

Showing the first eight; more decompositions exist.
