Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537126, here are decompositions:

29 + 31537097 = 31537126
83 + 31537043 = 31537126
167 + 31536959 = 31537126
263 + 31536863 = 31537126
353 + 31536773 = 31537126
419 + 31536707 = 31537126
587 + 31536539 = 31537126
743 + 31536383 = 31537126

Showing the first eight; more decompositions exist.
