Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462472, here are decompositions:

31 + 31462441 = 31462472
109 + 31462363 = 31462472
199 + 31462273 = 31462472
331 + 31462141 = 31462472
523 + 31461949 = 31462472
631 + 31461841 = 31462472
661 + 31461811 = 31462472
709 + 31461763 = 31462472

Showing the first eight; more decompositions exist.
