Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537774, here are decompositions:

53 + 31537721 = 31537774
83 + 31537691 = 31537774
227 + 31537547 = 31537774
293 + 31537481 = 31537774
383 + 31537391 = 31537774
461 + 31537313 = 31537774
467 + 31537307 = 31537774
503 + 31537271 = 31537774

Showing the first eight; more decompositions exist.
