Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444760, here are decompositions:

37 + 31444723 = 31444760
43 + 31444717 = 31444760
79 + 31444681 = 31444760
223 + 31444537 = 31444760
271 + 31444489 = 31444760
283 + 31444477 = 31444760
307 + 31444453 = 31444760
409 + 31444351 = 31444760

Showing the first eight; more decompositions exist.
