Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552350, here are decompositions:

41 + 31552309 = 31552350
47 + 31552303 = 31552350
79 + 31552271 = 31552350
97 + 31552253 = 31552350
113 + 31552237 = 31552350
139 + 31552211 = 31552350
157 + 31552193 = 31552350
211 + 31552139 = 31552350

Showing the first eight; more decompositions exist.
