Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552374, here are decompositions:

23 + 31552351 = 31552374
71 + 31552303 = 31552374
103 + 31552271 = 31552374
137 + 31552237 = 31552374
163 + 31552211 = 31552374
167 + 31552207 = 31552374
181 + 31552193 = 31552374
317 + 31552057 = 31552374

Showing the first eight; more decompositions exist.
