Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552562, here are decompositions:

73 + 31552489 = 31552562
211 + 31552351 = 31552562
661 + 31551901 = 31552562
709 + 31551853 = 31552562
829 + 31551733 = 31552562
1153 + 31551409 = 31552562
1201 + 31551361 = 31552562
1213 + 31551349 = 31552562

Showing the first eight; more decompositions exist.
