Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552972, here are decompositions:

29 + 31552943 = 31552972
53 + 31552919 = 31552972
89 + 31552883 = 31552972
239 + 31552733 = 31552972
251 + 31552721 = 31552972
263 + 31552709 = 31552972
383 + 31552589 = 31552972
419 + 31552553 = 31552972

Showing the first eight; more decompositions exist.
