Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552294, here are decompositions:

23 + 31552271 = 31552294
41 + 31552253 = 31552294
83 + 31552211 = 31552294
101 + 31552193 = 31552294
167 + 31552127 = 31552294
317 + 31551977 = 31552294
353 + 31551941 = 31552294
467 + 31551827 = 31552294

Showing the first eight; more decompositions exist.
