Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462972, here are decompositions:

3 + 31462969 = 31462972
41 + 31462931 = 31462972
71 + 31462901 = 31462972
83 + 31462889 = 31462972
179 + 31462793 = 31462972
383 + 31462589 = 31462972
389 + 31462583 = 31462972
419 + 31462553 = 31462972

Showing the first eight; more decompositions exist.
