Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552762, here are decompositions:

29 + 31552733 = 31552762
41 + 31552721 = 31552762
53 + 31552709 = 31552762
173 + 31552589 = 31552762
359 + 31552403 = 31552762
491 + 31552271 = 31552762
509 + 31552253 = 31552762
569 + 31552193 = 31552762

Showing the first eight; more decompositions exist.
