Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462676, here are decompositions:

67 + 31462609 = 31462676
73 + 31462603 = 31462676
97 + 31462579 = 31462676
103 + 31462573 = 31462676
313 + 31462363 = 31462676
337 + 31462339 = 31462676
409 + 31462267 = 31462676
607 + 31462069 = 31462676

Showing the first eight; more decompositions exist.
