Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552626, here are decompositions:

5 + 31552621 = 31552626
23 + 31552603 = 31552626
37 + 31552589 = 31552626
47 + 31552579 = 31552626
73 + 31552553 = 31552626
89 + 31552537 = 31552626
137 + 31552489 = 31552626
139 + 31552487 = 31552626

Showing the first eight; more decompositions exist.
