Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552782, here are decompositions:

61 + 31552721 = 31552782
73 + 31552709 = 31552782
89 + 31552693 = 31552782
101 + 31552681 = 31552782
139 + 31552643 = 31552782
179 + 31552603 = 31552782
193 + 31552589 = 31552782
229 + 31552553 = 31552782

Showing the first eight; more decompositions exist.
