Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552736, here are decompositions:

3 + 31552733 = 31552736
43 + 31552693 = 31552736
97 + 31552639 = 31552736
157 + 31552579 = 31552736
199 + 31552537 = 31552736
307 + 31552429 = 31552736
349 + 31552387 = 31552736
433 + 31552303 = 31552736

Showing the first eight; more decompositions exist.
