Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573670, here are decompositions:

31 + 31573639 = 31573670
43 + 31573627 = 31573670
109 + 31573561 = 31573670
157 + 31573513 = 31573670
277 + 31573393 = 31573670
307 + 31573363 = 31573670
313 + 31573357 = 31573670
409 + 31573261 = 31573670

Showing the first eight; more decompositions exist.
