Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522946, here are decompositions:

73 + 31522873 = 31522946
199 + 31522747 = 31522946
229 + 31522717 = 31522946
277 + 31522669 = 31522946
283 + 31522663 = 31522946
313 + 31522633 = 31522946
349 + 31522597 = 31522946
397 + 31522549 = 31522946

Showing the first eight; more decompositions exist.
